""" | ||||
Simple man page writer for reStructuredText. | ||||
Man pages (short for "manual pages") contain system documentation on unix-like | ||||
systems. The pages are grouped in numbered sections: | ||||
1 executable programs and shell commands | ||||
2 system calls | ||||
3 library functions | ||||
4 special files | ||||
5 file formats | ||||
6 games | ||||
7 miscellaneous | ||||
8 system administration | ||||
Man pages are written *troff*, a text file formatting system. | ||||
See http://www.tldp.org/HOWTO/Man-Page for a start. | ||||
Man pages have no subsection only parts. | ||||
