| 24 | # ==================== |
|---|
| 25 | # In 'configure.ac', include this file and call 'MY_VERSION_early' |
|---|
| 26 | # before 'AC_INIT'. After AC_INIT you can call MY_VERSION in order to |
|---|
| 27 | # AC_SUBST and AC_DEFINE variables MAJOR_VERSION, MINOR_VERSION etc. |
|---|
| 28 | # m4_include([m4/version.m4]) |
|---|
| 29 | # MY_VERSION_early([3],[1],[4],[true]) |
