% linuxdoctr 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.
