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'. | |
