cgi.c is a simple set of CGI manipulation routines

wsmbconf.c is a rudimentary web based smb.conf editor. Its really
there just to demonstrate how such an editor can hook into loadparm.c,
I don't expect anyone to actually use it as is.

wsmbstatus.c is a simple web based smbstatus. Its probably broken.
(This used to be commit ced5205f72ba58d677f3cfa480fddc58ec9faa27)
