Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AX_SPEC_FILE [(rpmspecfile [,subdirpath])]</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
set the specfile - if no argument has been given then check whether the
ac_unique_file looks like a .spec file and use it. This macro is
ac_REQUIRED by many AX_SPEC_ routines.
</p>
<p>
the AX_SPEC_EXTRACT macro is a helper used by many AX_SPEC_ routines and
therefore placed here to be automatically included in the macro set of
(older) aclocal/acinclude.
