| # About this script: |
| # This script is intended to simplify creating Subversion releases, by |
| # automating as much as is possible. It works well with our Apache |
| # infrastructure, and should make rolling, posting, and announcing |
| # releases dirt simple. |
| # |
| # This script may be run on a number of platforms, but it is intended to |
| # be run on people.apache.org. As such, it may have dependencies (such |
| # as Python version) which may not be common, but are guaranteed to be |
| # available on people.apache.org. |
| |
| # It'd be kind of nice to use the Subversion python bindings in this script, |
| # but people.apache.org doesn't currently have them installed |
| |
| # Stuff we need |
