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)
