Revision 1.1, Thu May 4 22:16:09 2017 UTC (4 years, 5 months ago) by schwarze
Branch: MAIN

Start roff formatter modules for HTML and termininal output,
used by both the mdoc and man formatters, with the ultimate
goal of reducing code duplication between the two macro formatters.
Made possible by the parser unification.
Add the first formatting function (for the .br request).
