Subject: cgi.c is a simple set of CGI manipulation routines
X-Git-Url: http://git.samba.org/samba.git/?p=kai%2Fsamba.git;a=commitdiff_plain;h=926f4d9125fa76d54e9abeba372ee78e9545182b;hp=aae64a93176feef6231638d0ded9838482b16adb;ds=inline

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)
