The current version of +@command{auto-auto-complete} can use such files to generate +auto-completion scripts for the @command{bash}, @command{zsh} +and @command{fish} shells. + +@command{auto-auto-complete}'s language limited in comparsion +to for example raw auto-completion scripts for the @command{bash} +shell, however it is well enough for most projects. + + + +@node Invoking +@chapter Invoking + +@command{auto-auto-complete} recognises two options: + +@table @option +@item -o +@itemx --output OUTPUT_FILE +Specifies the pathname of the generated file. + +@item -s +@itemx -f +@itemx --file +@itemx --source SOURCE_FILE +Specifies the pathname of the auto-auto-complete script. +@end table + +Both of these options must be used. Additionally +the shell that the generate file should be generated +for must be specified; this is done by adding name +of the shell as a stand-along argument, for example +@command{auto-auto-complete bash --output mycmd.bash --source mycmd.autocomplete} + +It is also possible to define variables that can be +used the auto-auto-complete script. If you, for example, +want to give the variable @var{command} the value +@code{mycmd}, add the argument @option{command=mycmd}. +It is also possible to define arrays, for example +if you want the variable @var{srcopt} to be an array +of the for values @code{-s}, @code{-f}, @code{--source} +and @code{--file}, add the arguments @option{srcopt=-s}, +@option{srcopt=-f}, @option{srcopt=--source} and +@option{srcopt=--file}. It is not possible to have +variable whose name begin with a dash (`-'). + +Alternatively you can run +@command{auto-auto-complete SHELL --where COMMAND} +(alternatively with @option{-w} instead of +@option{--where}). This will print the pathname +you should use for the generated file when installing +it. However the path prefix will not be included, +so if your package is installed to @file{/usr} +@footnote{The command being installed to @file{/usr/bin} +or @file{/usr/sbin}.}, you sould prepend @file{/usr} +to the output. + + + +@node Syntax +@chapter Syntax + +@command{auto-auto-complete} uses a LISP-like free form +syntax. Valid whitespace is normal blank space, horizontal +tab space@footnote{Also know simply as tab.}, +carriage return@footnote{The first character in a new line +in for example the HTTP protocol and in Window's encoding +for new lines, it was the new line character in the classical +Mac operating systems}, line feed (new line) and form feed +(new page). Comments can be started with either a semicolon +(;) or a hash (#). Comments end at the next following +new line, which may either be a carriage return, line feed +or form feed. Comments cannot be started inside quotes. + +The backslash character (\) can be used to force the +following character to be parsed verbatim, this is called +escaping. It is highly discourage to use this to escape +new lines, especially if the new line encoding used in the +document is carrige return–line feed, as that would only +escape the carrige return. There is also a set of characters +that have a special meaning when they are escaped: + +@table @asis +@item a +Audible bell character. +@item b +Backspace character. +@item e +Escape character. +@item f +Form feed character. +@item n +Line feed character. +@item r +Carriage character. +@item t +Horizontal tab space character. +@item v +Vertical tab space character. +@item 0 +Null character. +@end table + +Quotes, either simple quotes (') or double quotes (") +can be used to parse all character verbatim except +backslash (\). A quote ends at the next quote character +that is not escaped by a backslash (\) and is identical +to the opening quote character. This is especially useful +for escaping whitespace and round brackets. + +The rest of this chapter will demonstrate how to write a +script by example of @command{ponysay} (because it uses +most of the syntax). + +The first thing we do is to declare which command the +script is for. We do this by creating the root brackets +and put the name of the command as the first element. + +@example +(ponysay) +@end example + +However, @command{ponysay} has a very similar command +called @command{ponythink}. It is sensible to let the +same script be used for auto-complete for both commands, +to do this we utilise that we can define variables +when we invoke @command{auto-auto-complete}. + +@example +((value command)) +@end example + +Now when we compile this script we need invoke +@command{auto-auto-complete} with either +@option{command=ponysay} or @option{command=ponythink}. +If we want @command{ponysay} to be used if we +do not specify a value for @var{command} we instead +write: + +@example +((value command ponysay)) +@end example + +Remember that we could give a variable multiple values. +This can also be done here. However in this example +we only want one value. For example, @command{((value var a b))} +would generate @command{(a b)} if @var{var} has not been set. + +@command{ponysay} recognises the options @option{-h} and +@option{--help} for printing a summary of recognised options. +These options does not take any arguments and hence are specified +with @code{(unargumented)}. + +@example +((value command ponysay) + (unargumented (options -h --help) + (desc 'Show summary of options')) +) +@end example + +This only specifies that these option exists, if we also want +the generated scripts to suggest @option{--help} we need to +add @code{(complete --help)}. + +@example +((value command ponysay) + (unargumented (options -h --help) + (complete --help) + (desc 'Show summary of options')) +) +@end example + +Now that we have our first option, lets add a few others, to +keep the example short, we will skip the most of the options. + +@example +((value command ponysay) + (unargumented (options -h --help) + (complete --help) + (desc 'Show summary of options')) + (unargumented (options -l --list) + (complete --list) + (desc 'List all MLP:FiM ponies')) + (unargumented (options +l ++list) + (complete ++list) + (desc 'List all non-MLP:FiM ponies')) + (unargumented (options -X --256-colours --256colours --x-colours) + (desc 'Use xterm colours')) +) +@end example + +Now (especially if we had added all options) we have many +@code{(unargumented)} blocks. We can use @code{(multiple)} +so we do not have to write @code{unargumented} so many times. + +@example +((value command ponysay) + (multiple unargumented + ((options -h --help) (complete --help) + (desc 'Show summary of options')) + ((options -l --list) (complete --list) + (desc 'List all MLP:FiM ponies')) + ((options +l ++list) (complete ++list) + (desc 'List all non-MLP:FiM ponies')) + ((options -X --256-colours --256colours --x-colours) + (desc 'Use xterm colours')) + ) +) +@end example + +To keep this example short we will truncate this to: + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. +) +@end example + +@command{ponysay} also have a number of options that does +take an argument. We will add a few of them. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) + (desc 'Specify wrapping column')) + ((options +c --colour) (complete --colour) + (desc 'Specify colour of the balloon, balloon link and message')) + ) +) +@end example + +Just like @command{ponysay --help} prints @code{--wrap COLUMN} +to indicate that the argument for @option{--wrap} is is an +index of the column where the message printed by @command{ponysay} +is wrapped, shells could display the text @code{COLUMN} as +a placeholder for the next argument when you have typed +@option{--wrap}. To enable this in shells that support it, +we use @code{(arg)}. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) (arg PONY) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) (arg COLUMN) + (desc 'Specify wrapping column)') + ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) + (desc 'Specify colour of the balloon, balloon link and message')) + ) +) +@end example + +The next step now is to specify the type of argument the options +want. To do this we use @code{(files)}. The elements in @code{(files)} +specify what type of file the shell should suggest. Multiple +type can be used. Tehe recognsied ones are: + +@table @code +@item -0 +Do not suggest files, or do not suggest files of types specified +after @code{-0}. +@item -a +Suggest all files. +@item -f +Suggest regular files and pipes. +@item -r +Suggest regular files but not pipes. +@item -d +Suggest directories. +@item -l +Suggest symlinks. This is suggest by default, +but @code{-0} can be used to stop this. +@item -s +Suggest sockets. +@item -D +Suggest doors. +@end table + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) (arg PONY) + (files -f) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) + (files -f) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) (arg COLUMN) + (files -0) + (desc Specify wrapping column)) + ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) + (files -0) + (desc 'Specify colour of the balloon, balloon link and message')) + ) +) +@end example + +@code{(files)} can also be used to specify patterns (using +@code{sh}-globbing) for the filenames of the files to suggest. +For example @code{--pony} in @command{ponysay} should only, +in respect to files, suggest files that end with @code{.pony}. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) (arg PONY) + (files -f *.pony) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) + (files -f *.say) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) (arg COLUMN) + (files -0) + (desc Specify wrapping column)) + ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) + (files -0) + (desc 'Specify colour of the balloon, balloon link and message')) + ) +) +@end example + +For @option{--balloon} files ending with @code{.say} should be +suggested if the completion is for @command{ponysay}, but for +@command{ponythink} @code{.think}-files should be suggest. +We can use @code{(case)} to select this based on the value of +the first element in the root block, which is the name of the command. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) (arg PONY) + (files -f *.pony) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) + (files -f (case (ponysay *.say) (ponythink *.think))) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) (arg COLUMN) + (files -0) + (desc Specify wrapping column)) + ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) + (files -0) + (desc 'Specify colour of the balloon, balloon link and message')) + ) +) +@end example + +Another part of options with arguments is suggestions that are not +based on filenames. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented + ((options -f --file --pony) (complete --file --pony) (arg PONY) + (suggest pony-f) (files -f *.pony) + (desc 'Specify the pony that should printed')) + ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) + (suggest balloon) + (files -f (case (ponysay *.say) (ponythink *.think))) + (desc 'Specify message balloon style')) + ((options -W --wrap) (complete --wrap) (arg COLUMN) + (suggest wrap) (files -0) + (desc Specify wrapping column)) + ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) + (files -0) + (desc 'Specify colour of the balloon, balloon link and message')) + ) + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +Lets cut out the options again to make this shorter. + +@example +((value command ponysay) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented ...) ;We have cut out the options. + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +Another part of ponysay is that it will take also +argument that are not associated with an option make +make a message it prints out of thiat. + +@example +((value command ponysay) + (default (arg MESSAGE) (files -0) (suggest message) + (desc 'Message spoken by the pony')) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented ...) ;We have cut out the options. + (suggestion message) ;We will fill this in later... + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +A rather unusual part of @command{ponysay} is that +it has variadic options. A variadic option is a option +that takes all following arguments, unconditionally. +For example, in @command{ponysay} you can write +@code{--ponies twilight trixie} instead of +@code{--pony twilight --pony trixie}. @code{(variadic)} +is used to declare a variadic option. @code{(bind)} +becomes interesting here; because @command{ponysay}'s +variadic options have non-variadic counterparts, it +is pleasant to reuse the non-variadic options' +configurations. @code{(bind)} will copy everything +that is missing except @code{(options)} and +@code{(complete)}. In this example we will not +use @code{(complete)} because we do not want variadic +options to be suggest but we will use @code{(desc)} +because we want to adjust the descriptions. + +@example +((value command ponysay) + (default (arg MESSAGE) (files -0) (suggest message) + (desc 'Message spoken by the pony')) + (multiple unargumented ...) ;We have cut out the options. + (multiple argumented ...) ;We have cut out the options. + (variadic (options --f --files --ponies) (bind -f) + (desc 'Specify the ponies that may be printed')) + (suggestion message) ;We will fill this in later... + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +Notice that we used @code{-f} for the element in @code{(bind)}, +this is because we want @option{--f}, @option{--files} and +@code{--ponies} to have the same configurations (with exception +for the description) as the @option{-f} option. + +Once again, to make the example shorter we will cut out +some parts. + +@example +( ;We have cut out everything but the (suggestion):s. + (suggestion message) ;We will fill this in later... + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +For @code{(suggestion message)} we want the word +`MESSAGE' to be suggested to let the user know +that the non-option arguments make up the message +that is printed (if used). + +@example +( ;We have cut out everything but the (suggestion):s. + (suggestion message (verbatim MESSAGE)) + (suggestion pony-f) ;We will fill this in later... + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +For @code{(suggestion pony-f)} we want, in addition +to the .pony-files which as already been configured, +.pony-files from @file{/usr/share/ponysay/ponies} +to be suggested without the .pony-suffix. + +@example +( ;We have cut out everything but the (suggestion):s. + (suggestion message (verbatim MESSAGE)) + (suggestion pony-f (ls "'/usr/share/ponysay/ponies'" .pony)) + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +However, if the shell supports executing comments to +get suggetions we want to utilise this. + +@example +( ;We have cut out everything but the (suggestion):s. + (suggestion message (verbatim MESSAGE)) + (suggestion pony-f (exec "'/usr/bin/ponysay'" --onelist) + (noexec ls "'/usr/share/ponysay/ponies'" .pony)) + (suggestion balloon) ;We will fill this in later... + (suggestion wrap) ;We will fill this in later... +) +@end example + +@code{(suggestion balloon)} will work very similarly. + +@example +( ;We have cut out everything but the (suggestion):s. + (suggestion message (verbatim MESSAGE)) + (suggestion pony-f (exec "'/usr/bin/ponysay'" --onelist) + (noexec ls "'/usr/share/ponysay/ponies'" .pony)) + (suggestion balloon (exec "'/usr/bin/ponysay'" --balloonlist) + (no-exec ls "'/usr/share/ponysay/balloons'" + (case (ponysay .say) (ponythink .think)))) + (suggestion wrap) ;We will fill this in later... +) +@end example + +The first thing we want to do for @option{--wrap} +is to give it some default suggestion. + +@example +( ;We have cut out everything but (suggestion wrap). + (suggestion wrap (verbatim none inherit 100 60)) +) +@end example + +The next step is to suggest the terminal's +width minus 10 columns.

For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +The ``publisher'' means any person or entity that distributes copies +of the Document to the public. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy's public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. + +@item +RELICENSING + +``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server. A +``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the +site means any set of copyrightable works thus published on the MMC +site. + +``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0 +license published by Creative Commons Corporation, a not-for-profit +corporation with a principal place of business in San Francisco, +California, as well as future copyleft versions of that license +published by that same organization. + +``Incorporate'' means to publish or republish a Document, in whole or +in part, as part of another Document. + +An MMC is ``eligible for relicensing'' if it is licensed under this +License, and if all works that were first published under this License +somewhere other than this MMC, and subsequently incorporated in whole +or in part into the MMC, (1) had no cover texts or invariant sections, +and (2) were thus incorporated prior to November 1, 2008. + +The operator of an MMC Site may republish an MMC contained in the site +under CC-BY-SA on the same site at any time before August 1, 2009, +provided the MMC is eligible for relicensing. + +@end enumerate + +@page +@heading ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + +@smallexample +@group + Copyright (C) @var{year} @var{your name}. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

The current version of -@command{auto-auto-complete} can use such files to generate -auto-completion scripts for the @command{bash}, @command{zsh} -and @command{fish} shells. - -@command{auto-auto-complete}'s language limited in comparsion -to for example raw auto-completion scripts for the @command{bash} -shell, however it is well enough for most projects. - - - -@node Invoking -@chapter Invoking - -@command{auto-auto-complete} recognises two options: - -@table @option -@item -o -@itemx --output OUTPUT_FILE -Specifies the pathname of the generated file. - -@item -s -@itemx -f -@itemx --file -@itemx --source SOURCE_FILE -Specifies the pathname of the auto-auto-complete script. -@end table - -Both of these options must be used. Additionally -the shell that the generate file should be generated -for must be specified; this is done by adding name -of the shell as a stand-along argument, for example -@command{auto-auto-complete bash --output mycmd.bash --source mycmd.autocomplete} - -It is also possible to define variables that can be -used the auto-auto-complete script. If you, for example, -want to give the variable @var{command} the value -@code{mycmd}, add the argument @option{command=mycmd}. -It is also possible to define arrays, for example -if you want the variable @var{srcopt} to be an array -of the for values @code{-s}, @code{-f}, @code{--source} -and @code{--file}, add the arguments @option{srcopt=-s}, -@option{srcopt=-f}, @option{srcopt=--source} and -@option{srcopt=--file}. It is not possible to have -variable whose name begin with a dash (`-'). - -Alternatively you can run -@command{auto-auto-complete SHELL --where COMMAND} -(alternatively with @option{-w} instead of -@option{--where}). This will print the pathname -you should use for the generated file when installing -it. However the path prefix will not be included, -so if your package is installed to @file{/usr} -@footnote{The command being installed to @file{/usr/bin} -or @file{/usr/sbin}.}, you sould prepend @file{/usr} -to the output. - - - -@node Syntax -@chapter Syntax - -@command{auto-auto-complete} uses a LISP-like free form -syntax. Valid whitespace is normal blank space, horizontal -tab space@footnote{Also know simply as tab.}, -carriage return@footnote{The first character in a new line -in for example the HTTP protocol and in Window's encoding -for new lines, it was the new line character in the classical -Mac operating systems}, line feed (new line) and form feed -(new page). Comments can be started with either a semicolon -(;) or a hash (#). Comments end at the next following -new line, which may either be a carriage return, line feed -or form feed. Comments cannot be started inside quotes. - -The backslash character (\) can be used to force the -following character to be parsed verbatim, this is called -escaping. It is highly discourage to use this to escape -new lines, especially if the new line encoding used in the -document is carrige return–line feed, as that would only -escape the carrige return. There is also a set of characters -that have a special meaning when they are escaped: - -@table @asis -@item a -Audible bell character. -@item b -Backspace character. -@item e -Escape character. -@item f -Form feed character. -@item n -Line feed character. -@item r -Carriage character. -@item t -Horizontal tab space character. -@item v -Vertical tab space character. -@item 0 -Null character. -@end table - -Quotes, either simple quotes (') or double quotes (") -can be used to parse all character verbatim except -backslash (\). A quote ends at the next quote character -that is not escaped by a backslash (\) and is identical -to the opening quote character. This is especially useful -for escaping whitespace and round brackets. - -The rest of this chapter will demonstrate how to write a -script by example of @command{ponysay} (because it uses -most of the syntax). - -The first thing we do is to declare which command the -script is for. We do this by creating the root brackets -and put the name of the command as the first element. - -@example -(ponysay) -@end example - -However, @command{ponysay} has a very similar command -called @command{ponythink}. It is sensible to let the -same script be used for auto-complete for both commands, -to do this we utilise that we can define variables -when we invoke @command{auto-auto-complete}. - -@example -((value command)) -@end example - -Now when we compile this script we need invoke -@command{auto-auto-complete} with either -@option{command=ponysay} or @option{command=ponythink}. -If we want @command{ponysay} to be used if we -do not specify a value for @var{command} we instead -write: - -@example -((value command ponysay)) -@end example - -Remember that we could give a variable multiple values. -This can also be done here. However in this example -we only want one value. For example, @command{((value var a b))} -would generate @command{(a b)} if @var{var} has not been set. - -@command{ponysay} recognises the options @option{-h} and -@option{--help} for printing a summary of recognised options. -These options does not take any arguments and hence are specified -with @code{(unargumented)}. - -@example -((value command ponysay) - (unargumented (options -h --help) - (desc 'Show summary of options')) -) -@end example - -This only specifies that these option exists, if we also want -the generated scripts to suggest @option{--help} we need to -add @code{(complete --help)}. - -@example -((value command ponysay) - (unargumented (options -h --help) - (complete --help) - (desc 'Show summary of options')) -) -@end example - -Now that we have our first option, lets add a few others, to -keep the example short, we will skip the most of the options. - -@example -((value command ponysay) - (unargumented (options -h --help) - (complete --help) - (desc 'Show summary of options')) - (unargumented (options -l --list) - (complete --list) - (desc 'List all MLP:FiM ponies')) - (unargumented (options +l ++list) - (complete ++list) - (desc 'List all non-MLP:FiM ponies')) - (unargumented (options -X --256-colours --256colours --x-colours) - (desc 'Use xterm colours')) -) -@end example - -Now (especially if we had added all options) we have many -@code{(unargumented)} blocks. We can use @code{(multiple)} -so we do not have to write @code{unargumented} so many times. - -@example -((value command ponysay) - (multiple unargumented - ((options -h --help) (complete --help) - (desc 'Show summary of options')) - ((options -l --list) (complete --list) - (desc 'List all MLP:FiM ponies')) - ((options +l ++list) (complete ++list) - (desc 'List all non-MLP:FiM ponies')) - ((options -X --256-colours --256colours --x-colours) - (desc 'Use xterm colours')) - ) -) -@end example - -To keep this example short we will truncate this to: - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. -) -@end example - -@command{ponysay} also have a number of options that does -take an argument.

This is suggest by default, -but @code{-0} can be used to stop this. -@item -s -Suggest sockets. -@item -D -Suggest doors. -@end table - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented - ((options -f --file --pony) (complete --file --pony) (arg PONY) - (files -f) - (desc 'Specify the pony that should printed')) - ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) - (files -f) - (desc 'Specify message balloon style')) - ((options -W --wrap) (complete --wrap) (arg COLUMN) - (files -0) - (desc Specify wrapping column)) - ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) - (files -0) - (desc 'Specify colour of the balloon, balloon link and message')) - ) -) -@end example - -@code{(files)} can also be used to specify patterns (using -@code{sh}-globbing) for the filenames of the files to suggest. -For example @code{--pony} in @command{ponysay} should only, -in respect to files, suggest files that end with @code{.pony}. - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented - ((options -f --file --pony) (complete --file --pony) (arg PONY) - (files -f *.pony) - (desc 'Specify the pony that should printed')) - ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) - (files -f *.say) - (desc 'Specify message balloon style')) - ((options -W --wrap) (complete --wrap) (arg COLUMN) - (files -0) - (desc Specify wrapping column)) - ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) - (files -0) - (desc 'Specify colour of the balloon, balloon link and message')) - ) -) -@end example - -For @option{--balloon} files ending with @code{.say} should be -suggested if the completion is for @command{ponysay}, but for -@command{ponythink} @code{.think}-files should be suggest. -We can use @code{(case)} to select this based on the value of -the first element in the root block, which is the name of the command. - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented - ((options -f --file --pony) (complete --file --pony) (arg PONY) - (files -f *.pony) - (desc 'Specify the pony that should printed')) - ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) - (files -f (case (ponysay *.say) (ponythink *.think))) - (desc 'Specify message balloon style')) - ((options -W --wrap) (complete --wrap) (arg COLUMN) - (files -0) - (desc Specify wrapping column)) - ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) - (files -0) - (desc 'Specify colour of the balloon, balloon link and message')) - ) -) -@end example - -Another part of options with arguments is suggestions that are not -based on filenames. - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented - ((options -f --file --pony) (complete --file --pony) (arg PONY) - (suggest pony-f) (files -f *.pony) - (desc 'Specify the pony that should printed')) - ((options -b --bubble --balloon) (complete --balloon) (arg STYLE) - (suggest balloon) - (files -f (case (ponysay *.say) (ponythink *.think))) - (desc 'Specify message balloon style')) - ((options -W --wrap) (complete --wrap) (arg COLUMN) - (suggest wrap) (files -0) - (desc Specify wrapping column)) - ((options +c --colour) (complete --colour) (arg ANSI-COLOUR) - (files -0) - (desc 'Specify colour of the balloon, balloon link and message')) - ) - (suggestion pony-f) ;We will fill this in later... - (suggestion balloon) ;We will fill this in later... - (suggestion wrap) ;We will fill this in later... -) -@end example - -Lets cut out the options again to make this shorter. - -@example -((value command ponysay) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented ...) ;We have cut out the options. - (suggestion pony-f) ;We will fill this in later... - (suggestion balloon) ;We will fill this in later... - (suggestion wrap) ;We will fill this in later... -) -@end example - -Another part of ponysay is that it will take also -argument that are not associated with an option make -make a message it prints out of thiat. - -@example -((value command ponysay) - (default (arg MESSAGE) (files -0) (suggest message) - (desc 'Message spoken by the pony')) - (multiple unargumented ...) ;We have cut out the options. - (multiple argumented ...) ;We have cut out the options. - (suggestion message) ;We will fill this in later... - (suggestion pony-f) ;We will fill this in later... - (suggestion balloon) ;We will fill this in later... - (suggestion wrap) ;We will fill this in later... -) -@end example - -A rather unusual part of @command{ponysay} is that -it has variadic options. A variadic option is a option -that takes all following arguments, unconditionally. -For example, in @command{ponysay} you can write -@code{--ponies twilight trixie} instead of -@code{--pony twilight --pony trixie}. @code{(variadic)} -is used to declare a variadic option. @code{(bind)} -becomes interesting here; because @command{ponysay}'s -variadic options have non-variadic counterparts, it -is pleasant to reuse the non-variadic options' -configurations. @code{(bind)} will copy everything -that is missing except @code{(options)} and -@code{(complete)}.

We recommend this License -principally for works whose purpose is instruction or reference. - -@item -APPLICABILITY AND DEFINITIONS - -This License applies to any manual or other work, in any medium, that -contains a notice placed by the copyright holder saying it can be -distributed under the terms of this License. Such a notice grants a -world-wide, royalty-free license, unlimited in duration, to use that -work under the conditions stated herein. The ``Document'', below, -refers to any such manual or work. Any member of the public is a -licensee, and is addressed as ``you''. You accept the license if you -copy, modify or distribute the work in a way requiring permission -under copyright law. - -A ``Modified Version'' of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A ``Secondary Section'' is a named appendix or a front-matter section -of the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall -subject (or to related matters) and contains nothing that could fall -directly within that overall subject. (Thus, if the Document is in -part a textbook of mathematics, a Secondary Section may not explain -any mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The ``Invariant Sections'' are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. If a -section does not fit the above definition of Secondary then it is not -allowed to be designated as Invariant. The Document may contain zero -Invariant Sections. If the Document does not identify any Invariant -Sections then there are none. - -The ``Cover Texts'' are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. A Front-Cover Text may -be at most 5 words, and a Back-Cover Text may be at most 25 words. - -A ``Transparent'' copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, that is suitable for revising the document -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup, or absence of markup, has been arranged to thwart -or discourage subsequent modification by readers is not Transparent. -An image format is not Transparent if used for any substantial amount -of text. A copy that is not ``Transparent'' is called ``Opaque''. - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, La@TeX{} input -format, SGML or XML using a publicly available -DTD, and standard-conforming simple HTML, -PostScript or PDF designed for human modification. Examples -of transparent image formats include PNG, XCF and -JPG. Opaque formats include proprietary formats that can be -read and edited only by proprietary word processors, SGML or -XML for which the DTD and/or processing tools are -not generally available, and the machine-generated HTML, -PostScript or PDF produced by some word processors for -output purposes only. - -The ``Title Page'' means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, ``Title Page'' means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - -The ``publisher'' means any person or entity that distributes copies -of the Document to the public. - -A section ``Entitled XYZ'' means a named subunit of the Document whose -title either is precisely XYZ or contains XYZ in parentheses following -text that translates XYZ in another language. (Here XYZ stands for a -specific section name mentioned below, such as ``Acknowledgements'', -``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' -of such a section when you modify the Document means that it remains a -section ``Entitled XYZ'' according to this definition. - -The Document may include Warranty Disclaimers next to the notice which -states that this License applies to the Document. These Warranty -Disclaimers are considered to be included by reference in this -License, but only as regards disclaiming warranties: any other -implication that these Warranty Disclaimers may have is void and has -no effect on the meaning of this License. - -@item -VERBATIM COPYING - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies.

Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a computer-network location from which the general network-using -public has access to download using public-standard network protocols -a complete Transparent copy of the Document, free of added material. -If you use the latter option, you must take reasonably prudent steps, -when you begin distribution of Opaque copies in quantity, to ensure -that this Transparent copy will remain thus accessible at the stated -location until at least one year after the last time you distribute an -Opaque copy (directly or through your agents or retailers) of that -edition to the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - -@item -MODIFICATIONS - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it.

These may be placed in the ``History'' section. -You may omit a network location for a work that was published at -least four years before the Document itself, or if the original -publisher of the version it refers to gives permission. - -@item -For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve -the Title of the section, and preserve in the section all the -substance and tone of each of the contributor acknowledgements and/or -dedications given therein. - -@item -Preserve all the Invariant Sections of the Document, -unaltered in their text and in their titles. Section numbers -or the equivalent are not considered part of the section titles. - -@item -Delete any section Entitled ``Endorsements''. Such a section -may not be included in the Modified Version. - -@item -Do not retitle any existing section to be Entitled ``Endorsements'' or -to conflict in title with any Invariant Section. - -@item -Preserve any Warranty Disclaimers. -@end enumerate - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section Entitled ``Endorsements'', provided it contains -nothing but endorsements of your Modified Version by various -parties---for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - -@item -COMBINING DOCUMENTS - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice, and that you preserve all their Warranty Disclaimers. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy.

You may include a -translation of this License, and all the license notices in the -Document, and any Warranty Disclaimers, provided that you also include -the original English version of this License and the original versions -of those notices and disclaimers. In case of a disagreement between -the translation and the original version of this License or a notice -or disclaimer, the original version will prevail. - -If a section in the Document is Entitled ``Acknowledgements'', -``Dedications'', or ``History'', the requirement (section 4) to Preserve -its Title (section 1) will typically require changing the actual -title. - -@item -TERMINATION - -You may not copy, modify, sublicense, or distribute the Document -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense, or distribute it is void, and -will automatically terminate your rights under this License. - -However, if you cease all violation of this License, then your license -from a particular copyright holder is reinstated (a) provisionally, -unless and until the copyright holder explicitly and finally -terminates your license, and (b) permanently, if the copyright holder -fails to notify you of the violation by some reasonable means prior to -60 days after the cessation. - -Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - -Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, receipt of a copy of some or all of the same material does -not give you any rights to use it. - -@item -FUTURE REVISIONS OF THIS LICENSE - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. See -@uref{http://www.gnu.org/copyleft/}. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License ``or any later version'' applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation.
