doc: make sure we use our own code for generating man pages docutils would in some situations pick up its own manpage.py instead of doc/manpage.py. Renaming to hgmanpage.py makes it less ambiguous.

8 Simple man page writer for reStructuredText.
9
10 Man pages (short for "manual pages") contain system documentation on unix-like
11 systems. The pages are grouped in numbered sections:
12
13 1 executable programs and shell commands
14 2 system calls
15 3 library functions
16 4 special files
17 5 file formats
18 6 games
19 7 miscellaneous
20 8 system administration
21
22 Man pages are written *troff*, a text file formatting system.
23
24 See http://www.tldp.org/HOWTO/Man-Page for a start.
25
26 Man pages have no subsection only parts.
27 Standard parts

29 NAME ,

31 DESCRIPTION ,

39 AUTHOR .
40
41 A unix-like system keeps an index of the DESCRIPTIONs, which is accesable
42 by the command whatis or apropos.
