 hg-ssh - a wrapper for ssh access to a limited set of mercurial repos
 
 To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8):
 command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ...
 (probably together with these other useful options:
  no-port-forwarding,no-X11-forwarding,no-agent-forwarding)
 
 This allows pull/push over ssh from/to the repositories given as arguments.
 
 If all your repositories are subdirectories of a common directory, you can
 allow shorter paths with:
 command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2"
 
 You can use pattern matching of your normal shell, e.g.:
 command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}"

 """
 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 accesable
 by the command whatis or apropos.
