139 The groff documentation is scattered upon several places.
141 - The main directory contains documents related to the groff source.
142 The README file contains the information needed to get the groff
143 package, report bugs, and contact the developers.
145 - The man-page of each program (section 1) is kept in the source
146 directory of the program.
148 - The man-pages for the other sections are found in `src/man'.
150 - Documentation in other formats are located in the `doc' directory,
151 including the groff info file, tutorials, and manuals.
156 The parsing of the roff language is done by troff. The input is converted
157 to tokens in `src/roff/troff/input.cpp' and transformed into `nodes' by
158 `src/roff/troff/env.cpp' and `src/roff/troff/node.cpp'. From these, the
159 intermediate output is generated (also in `node.cpp').
164 The parser for the intermediate output and the postprocessing is in
165 `src/libs/libdriver/input.cpp'. This is used by all postprocessors.
