Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_DEFINE_VERSIONLEVEL(VARNAME [,VERSION [, DESCRIPTION]])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
if the VERSION is ommitted, shellvar $VERSION is used as defined by
AM_INIT_AUTOMAKE's second argument.
</p>
<p>
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.
</p>
<p>
typical usage: AM_INIT_AUTOMAKE(mypkg,4.12.3)
AC_DEFINE_VERSIONLEVEL(MYPKG_VERSION)
</p>
<p>
the config.h created from autoheader's config.h.in will contain... /* mypkg
versionlevel */ #define MYPKG_VERSION 4120003
</p>
<p>
the MYKG_VERSION will be defined as both a shell-variable and AC_DEFINE
</p>
