#
# makesrcdist - make a distribution of FLTK.
#
# There are 3 different modes of operation, dependent on commandline arguments:
#
#  (1)	Create snapshot:
#
#	makesrcdist [snapshot]
#
#	Use no arguments or "snapshot" (verbatim).
#
#  (2)	Create distribution tarballs for test and verification:
#
#	makesrcdist <version>
#
#	Use a version number as argument, e.g. "1.3.3" or "1.3.4rc2".
#	This can be used for local testing.
#
#	Note: the release tarballs will be created from the current
#	'HEAD' revision of your local Git repository.
#
#  (3)	Create distribution tarballs (final):
#
#	makesrcdist <version> tag
#
#	Same as (2), but create Git tag with version number.
#	Enter "tag" (verbatim) as 2nd argument.
#	This will create the Git tag "release-<version>" for the
#	current revision in the (local) FLTK Git repository and export the
#	FLTK sources from this tag for creation of distribution files.
#
#	Note: You need to 'git push' the Git tag manually when you
#	are satisfied with the result. You may use:
#	  $ git push origin release-<version>
#	where '<version>' is the version number (argument #1)
#
# Note: define FLTK_TAR if you want to use a different compatible tar
#	command than "tar", e.g. to use "gtar" (bash syntax):
#	$ export FLTK_TAR="gtar"
#
