guidod's Miscellaneous (released)

if the VERSION is ommitted, shellvar $VERSION is used as defined by AM_INIT_AUTOMAKE's second argument.

The versionlevel is the numeric representation of the given version string, thereby assuming the inputversion is a string with (maximal) three decimal numbers seperated by "."-dots. A "-patch" adds a percent.

typical usage: AM_INIT_AUTOMAKE(mypkg,4.12.3) AC_DEFINE_VERSIONLEVEL(MYPKG_VERSION)

the config.h created from autoheader's config.h.in will contain... /* mypkg versionlevel */ #define MYPKG_VERSION 4120003

the MYKG_VERSION will be defined as both a shell-variable and AC_DEFINE

examples:

      3.0-beta1     3000001
      3.1           3010000
