# Create source tarball from git repo, with generated version number.

# This is not a generic git2tarxz script, it's specific to gtetrinet.
# Upstream doesn't use tags for version bumps, so the version number
# is extracted from configure.ac.

# 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

## Config:
PRGNAM=gtetrinet
