|
# Calculates the current version number by first checking output of “git describe”,
|
|
# modified to conform to PEP 386 versioning scheme. If “git describe” fails
|
|
# (likely due to using release tarball rather than git working copy), then fall
|
|
# back on reading the contents of the RELEASE-VERSION file.
|
|
#
|
|
# Usage: Import in setup.py, and use result of get_version() as package version:
|
|
#
|
|
# from version import *
|
|
#
|
|
# setup(
|
|
# ...
|
|
# version=get_version(),
|
|
# ...
|
|
# )
|
|
#
|
|
# Script will automatically update the RELEASE-VERSION file, if needed.
|
|
# Note that RELEASE-VERSION file should *not* be checked into git; please add
|
|
# it to your top-level .gitignore file.
|
|
#
|
|
# You'll probably want to distribute the RELEASE-VERSION file in your
|
|
# sdist tarballs; to do this, just create a MANIFEST.in file that
|
|
# contains the following line:
|
|
#
|
|
# include RELEASE-VERSION
|
|
#
