+% linuxdoc replacement file
+% translates into nroff, using ms macros
+% manpages can be processed using the man macros
+% does not use neqn for math.
+
+% Based on qwertz replacement file by Tom Gordon
+% linuxdoc mods by mdw
+
+% Groff dependencies are few.  To port to another roff: 
+% 1. Check and modify, if necessary, font changes.  (e.g. In psroff the
+% same fonts have other names.)
+% 2. Check the code for including Encapsulated PostScript, generated
+% for eps elements.
+% 3. Also make versions of general.grops and math.grops, which are sed
+% scripts translating character entities into groff character references.
