"""
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
NAME ,
SYNOPSIS ,
DESCRIPTION ,
OPTIONS ,
FILES ,
SEE ALSO ,
BUGS ,
and
AUTHOR .
A unix-like system keeps an index of the DESCRIPTIONs, which is accessible
by the command whatis or apropos.
