Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_CHECK_DOCBOOK_XSLT_MIN(min-xslt-version)</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Check that the 'current' version of docbook is at least version
min-xslt-version. If the test is successful, $DOCBOOK_XSLT_CURRENT_VERSION
will be set to the current docbook version; if not, it will be set to 'no'.
</p>
<p>
Example:
</p>
<pre>
AC_CHECK_DOCBOOK_XSLT_MIN(1.72.0)
if test "x$DOCBOOK_XSLT_CURRENT_VERSION" = "xno"; then
