dnl AS_DOCBOOK([, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])

dnl checks if xsltproc can build docbook documentation
|
||
|
|
dnl (which is possible if the catalog is set up properly
|
||
|
|
dnl I also tried checking for a specific version and type of docbook
|
||
|
|
dnl but xsltproc seemed to happily run anyway, so we can't check for that
|

dnl and version
