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