ac_check_docbook_xslt

Check for access to docbook stylesheets of a particular revision. This macro can be used for multiple versions within the same script.

Input:

$1 is the version of docbook to search for; default 'current'.

Output:

$HAVE_DOCBOOK_XSLT_VERS will be set to 'yes' or 'no' depending on the results of the test, where VERS is $1, with '_' substituted for '.' $HAVE_DOCBOOK_XSLT will also be set to the same value.

Example:

 AC_CHECK_DOCBOOK_XSLT(1.72.0)
 if test "x$HAVE_DOCBOOK_XSLT_1_72_0" = "xyes"; then
 ...

AC_DEFUN([AC_CHECK_DOCBOOK_XSLT],
[
    AC_REQUIRE([AC_PROG_XSLTPROC])

    define([HAVE_DOCBOOK_XSLT_VERS], patsubst([HAVE_DOCBOOK_XSLT_]_VERS, [\.], [_]))
