## 6. More documentation

The programmer's manual is essential for concepts.

Nearly all the clients supplied come with a man page which is installed into `/usr/mgr/man/man1` or `man6`. Other useful man pages are `bitblit.3`, `font.5`, and `bitmap.5`. There is some ambiguity in the docs in distinguishing the internal bitmap format found in your frame-buffer and the external bitmap format found in files, e.g. icons.

The `mgr.1` man page covers command line options, commands in the `~/.mgrc` startup file, mouse and menu interaction with the server, and hot-key shortcuts available on systems with such hot-keys.

Many of the fonts in `/usr/mgr/font/*` are described to some extent in `/usr/mgr/font/*.txt`, e.g. `/usr/mgr/font/FONTDIR.txt` gives X-style font descriptions for the fonts obtained in .bdf format. Font names end in `WxH`, where `W` and `H` are the decimal width and height in pixels of each character box.
