|
||
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.
|
||
Standard parts
