source: trunk/configure.ac @ 944

Last change on this file since 944 was 944, checked in by Peter, 14 years ago

added test for presence for doxygen, latex, dvipdfm, and latex2html. If not found and configure is run in --enable-debug mode a warning is given. On default mode (non-debug) no warnings are given because if running configure in a distribution the documentation should already be there and a warning seems odd.
