# This git2tarxz has special case code for kmscon.
# Create source tarball from git repo, with generated version number.
# Takes one optional argument, which is the commit or tag to create a
# tarball of. With no arg, HEAD is used.
# Version number example: 0.0.1+20200227_ad7ec17
# Notes:
# Do not use this if you're packaging a release.
# This script doesn't need to be run as root. It does need to be able
# to write to the current directory it's run from.
# Running this script twice for the same commit will NOT give identical
# tarballs, even if the contents are identical. This is because tar
# includes the current time in a newly-created tarball (plus there may
# be other git-related reasons).
# Once you've generated a tarball, you'll still need a place to host it.
# Ask on the mailing list, if you don't have your own web server to
# play with.
## Config:
# final tarball and slackbuild PRGNAM:
PRGNAM=kmscon
# For github projects, you can use this unmodified:
CLONE_URL=git://people.freedesktop.org/~dvdhrm/kmscon
## End of config.
