Provide correct help URL.
2003-01-24 Glynn Foster <glynn.foster@sun.com> * src/about.c: Provide correct help URL. * src/util.h, src/util.c: Add functions from libgnome/gnome-i18n so that we can correctly find the apropriate help file. * xmldocs.make: Install help into $(datadir)/help/$(lang)/ * THANKS: Update from the code I stole from libgnome
