| | 3 | ### SYNOPSIS |
| | 4 | ### |
| | 5 | ### mdw_AUTO_VERSION |
| | 6 | ### |
| | 7 | ### DESCRIPTION |
| | 8 | ### |
| | 9 | ### Defines an m4 macro `AUTO_VERSION' which contains the current package's |
| | 10 | ### version number, worked out in some clever way. |
| | 11 | ### |
| | 12 | ### The heavy lifting is performed by the `auto-version' script (q.v.). In |
| | 13 | ### brief: |
| | 14 | ### |
| | 15 | ### * if this is a Git working tree (i.e., there is a `.git' file or |
| | 16 | ### directory at toplevel) then call `git describe' and use its output; |
| | 17 | ### |
| | 18 | ### * if there is a `RELEASE' file, then use its contents literally; |
| | 19 | ### |
| | 20 | ### * if there is a `debian/changelog' file, then use the most recent |
| | 21 | ### entry's version number; |
| | 22 | ### |
| | 23 | ### * otherwise use `UNKNOWN'. |
