+.SH DESCRIPTION
+The
+.B anysum
+utility can calculate checksums of a file using
+multiple hash functions, or using different parameters for
+the function, in parallel (the utility can calculate checksums
+for multiple files, but these are not calculated in parallel).
+.PP
+The
+.B anysum
+utility can also check a file against multiple
+checksums using multiple hash function and hash function
+parameters in parallel, and check that the file matches at
+least one of the listed checksums.

+behaviour for that file if the line
+specifies hexadecimal mode.
+.TP
+.BI threads= count
+The maximum number of threads that the
+utility may use. If
+.RB \(dq auto \(dq
+is specified, the utility selects a default
+value, which currently is the number of
+online CPU threads (at any time; assumed to
+be 8 if it cannot be determined) minus 2,

+.TP
+.BR -W \ \fIoptions\fP
+Comma-sepearated list of implementation-specific
+options. The following options are supported:
+.RS
+.TP
+.BI output= format
+.I format
+shall be
+.RB \(dq lowercase \(dq
+if the checksums shall be printed in lowercase
+hexadecimal format (default),
+.RB \(dq uppercase \(dq
+for uppercase hexadecimal format, or
+.RB \(dq binary \(dq
+for binary format without anything but the
+checksum printed to standard output. This
+option is ignored if the
+.B -c
+option is used.
+.TP
+.BI input= format
+.I format
+shall be
+.RB \(dq binary \(dq
+if the files are be read in binary mode,
+.RB \(dq text \(dq
+if the files shall be read in text mode, or
+.RB \(dq hexadecimal \(dq
+they shall be decoded from hexadecimal to
+binary. If the
+.B -c
+option is used, the mode specification
+associated with a file is overrides this
+behaviour for that file if the line
+specifies hexadecimal mode.
+.TP
+.B recursive
+If a
+.I file
+operand is a directory, the checksum is computed for
+all files recursively. This option is ignored if the
+.B -c
+option is used.
+.TP
+.B no-recursive
+The utility shall traverse directories.
+(This is the default behaviour).
+.TP
+.B xdev
+Implies
+.B -W recursive
+but also allows the recursion across mountpoints.
+.TP
+.B no-xdev
+Disable recursion across mountpoints.
+(This is the default behaviour).
+Note that this does not disable
+recursion by itself.
+.TP
+.B xlink
+Implies
+.B -W recursive
+but also allows the recursion across symbolic links.
+.TP
+.B no-xlink
+Disable recursion across symbolic links.
+(This is the default behaviour).
+Note that this does not disable
+recursion by itself.
+.RE
+.TP
+.B -w
+Warn about, but skip, lines that are not properly
+formatted.
+.TP
+.B -x
+Equivalent to
+.BR "-W input=hexadeximal" .
+.TP
+.B -z
+Use NUL byte as line ending instead of LF.
+.PP
+There is no difference between binary mode and text mode.
+
+.SH OPERANDS
+The following operand is supported:
+.TP
+.I file
+The file to read and compute the checksum for, or if the
+.B -c
+option is used, use as the listing of files and checksums
+to verify the files against. If dash
+.RB (' - ')
+is used or if no file operand is specified, standard input
+will be used.
+
+.SH STDOUT
+If the
+.B -c
+option is not used, the utility shall print the following
+line for each calculated checksum, however there are options
+that modify the format; see the
+.B OPTIONS
+section for more information:
+.PP
+.RS
+.B \(dq%s %c%s\en\(dq,
+.RI < hash >\fB,\fP
+.RI < mode >\fB,\fP
+.RI < file >
+.RE
+.PP
+where
+.I mode
+is SP (' ') for text mode, an asterisk
+.RB (' * ')
+for binary mode, or a pound sign
+.RB (' # ')
+for hexadecimal mode; however if there is no difference
+between binary mode and text mode and either is selected,
+SP (' ') (text mode) is used.
+.PP
+If the
+.B -c
+option the output shall be on the format:
+.PP
+.RS
+.B \(dq%s: %s\en\(dq,
+.RI < file >\fB,\fP
+.RI < validity >
+.RE
+.PP
+where
+.I validity
+is an implementation specified string
+that describes whether the checksum was valid (possibly
+with remarks), the file did not exist, the file could
+not be read (possibly with error information), or if
+the checksum was invalid or could not be compared
+(possibly with remarks). The
+.B -z
+option does not modify the line ending.
+
+.SH EXIT STATUS
+The following exit values are returned:
+.TP
+0
+Successful completion.
+.TP
+1
+Checksums did not match or a file did not exist.
+.TP
+2
+An error occurred.
+
+.SH NOTES
+Other implementations do not necessarily recognise the
+hexadecimal mode specifier
+.RB (' # ')
+in checksum list files.
+.PP
+The
+.B -c
+option accepting truncated checksums is an
+implementation-specific behaviour.
