-This is a collection of generic enough makefiles.
-Please feel free to use them in your project.
-
-Usage:
-	Include all.mk from your makefile.
-
-	Read the top of each file for details.
-
-	Define the variables:
-
-		_VERSION
-		This version of the package.
-
-		_PROJECT
-		The name of the project. Must only include [a-z0-9_-].
-
-		_PROJECT_FULL
-		The name of the project. May include any character.
-
-		_SRC
-		All source code files. This list is used when
-		generating the translation template file.
-
-		_COPYRIGHT_HOLDER
-		The copyright holder's full name and e-mail address.
-
-		COMMAND
-		The name of the command. Must not be declared if
-		the package does not include exactly one runnable
-		command.
-
-		PKGNAME
-		The name of the package.
-
-	Variables beginning with __ are used internally by
-	the files where they appear, or in rare cases,
-	internally between these files.
-
-	Variables beginning with _ but not __ are set in the
-	makefile to specify for these files how they should
-	behave. They should not be changed by a user of the
-	package.
-
-	Variables that do not begin with _ are configurable
-	by the user of the package.
-
-	Do no use single character variables in your Makefile.
-
-	To suppress pre-install, post-install, pre-uninstall,
-	and post-uninstall instructions, set N=true.
-	PRE_INSTALL, POST_INSTALL, PRE_UNINSTALL, and
-	POST_UNINSTALL are supportered as specified by the
-	GNU coding standardars.
-
-	To figure out what pre-install commands to run in your package, run:
-		 make -n a=% install | sed -e 's/\\$//' -e 's/^ *//' | sed -n '/^% /s/^..//p'
-
-	To figure out what post-install commands to run in your package, run:
-		 make -n z=% uninstall | sed -e 's/\\$//' -e 's/^ *//' | sed -n '/^% /s/^..//p'
-
-	To figure out what pre-uninstall commands to run in your package, run:
-		 make -n a=% uninstall | sed -e 's/\\$//' -e 's/^ *//' | sed -n '/^% /s/^..//p'
-
-	To figure out what post-uninstall commands to run in your package, run:
-		 make -n z=% uninstall | sed -e 's/\\$//' -e 's/^ *//' | sed -n '/^% /s/^..//p'
-
-	To suppress verbatim which commands Make runs,
-	set Q=@. (Excluding the period.)
-
-Developers should use DEBUG=1 when running make, when possible.

-

-# This file is ignored unless _C_STD is defined.
-# _C_STD should be set the the version of C that
-# is used.
-# 
-# If you want to compile with -pedantic, define
-# the variable _PEDANTIC.
-# 
-# Define _CPPFLAGS with any additional CPP
-# flags to use, _CFLAGS with any additional CC
-# flags to use, and _LDFLAGS with any additional
-# LD flags to use.
-# 
-# Defined in path.mk, you can change _ALL_DIRS
-# if you do not want CPP definitions for all
-# directories.
-# 
-# Define _HEADER_DIRLEVELS to specify the directory
-# nesting level in src. It is assumed that all
-# directories contain header files. Set to '0' if
-# there are no header files.
-# 
-# _BIN shall list all commands to build. These
-# should be the basenames. For each command
-# you should be the variable _OBJ_$(COMMAND)
-# that lists all objects files (without the
-# suffix and without the aux/ prefix) that
-# are required to build the command.
-# 
-# Binary you want installed to /sbin rather than
-# /bin shall be listed in _SBIN rather than in
-# _BIN. _SBIN and _BIN may not list binaries
-# with identical names. Analogically, you may
-# add _LIBEXEC for binary to be installed to
-# /libexec.
-# 
-# If you only have one binary, you may select
-# to define _BINDIR to name the variable with
-# the pathname for the directory the binary
-# shall be installed. For example, if you want
-# the binary to be installed to /usr/sbin,
-# define _BINDIR = SBINDIR.
-# 
-# List libraries to compile in in _LIB. For each
-# library, sould should also define
-# _SO_VERSION_$(LIBRARY) and _SO_MAJOR_$(LIBRARY)
-# with the full version number and the major
-# version number, respectively. Additionally,
-# list all header files that shall be installed
-# in _H, these should not contain the 'src/' prefix
-# or the '.h' suffix.
