| # 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 | |
| # | |
