1998-12-02 Havoc Pennington <hp@pobox.com> * testgdate.c, testgdateparser.c: Two new files. This is kind of ugly code, but I want to go ahead and make the tests available. It isn't contaminating any other code. :-) Since one of these is interactive and the other takes a while to run, I've kept them separate from testglib for now. * Makefile.am: Build gdate test programs.
