Support to generate cross-platform Makefiles using autotools
        The first time you checkout the repository you need to generate
	the 'configure' script and the 'Makefile.in' templates by running:
        $ sh autogen.sh
	This script will generate the 'configure' script and the 'Makefile.in' templates
	from configure.ac and Makefile.am. It will also  call the 'configure' script for you,
	which will generate all the 'Makefile' files from the 'Makefile.in' templates.
	'autogen.sh' should be called for each change in configure.ac or Makefile.am files.
	This script is targetted for developpers, to avoid polluting the repository with
	extra files.
	After running 'autogen.sh' once, you will usually use the following commands:
 	$ ./configure
	$ make
	# make install
	You can create a tarball for the current version (stored in configure.ac) using:
	$ make dist
