makesrcdist

#!/bin/sh
#
# 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> <doc-dir>
#
#     <version> : Use a version number as argument, e.g. "1.3.3" or "1.3.4rc2".
#     This can be used for local testing.
#
#     <doc-dir> : This *MUST* be a CMake build folder where all the
#     documentation (HTML, PDF, Fluid-HTML, and Fluid-PDF) were built.
#     The directory name can be relative to the FLTK root or absolute.
#
#     Note: the release tarballs will be created from the current
#     'HEAD' revision of your local Git repository. Make sure that
#     you committed all changes.
#
# (3) Create distribution tarballs (final):
#
#     ./makesrcdist <version> <doc-dir> tag
#
#     Same as (2), but create Git tag with version number.
#     Enter "tag" (verbatim) as 3rd 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 <origin> is your remote repository, e.g. "origin" or "upstream"
#     and <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"
#
