Subject: [PATCH] gitweb: fill in gitweb configuration by Makefile

From: Martin Waitz <[email-masked]>
Date: Mon, 31 Jul 2006 00:37:54 +0200

Generate gitweb/gitweb.cgi to reduce the need to patch gitweb.cgi by
the end user.
The GIT installation directory and version are already known by the
Makefile, they can be inserted directly into gitweb.
All other gitweb configuration parameters can now be specified
by providing GITWEB_* variables while building GIT.
These are described in gitweb/README.

 From the git version 1.4.0 gitweb is bundled with git.
 
+
+How to configure gitweb for your local system:
+
+You can specify the following configuration variables when building GIT:
+ * GITWEB_SITENAME
+   Shown in the title of all generated pages, defaults to the servers name.
+ * GITWEB_PROJECTROOT
+   The root directory for all projects shown by gitweb.
+ * GITWEB_LIST
+   points to a directory to scan for projects (defaults to project root)
+   or to a file for explicit listing of projects.
+ * GITWEB_HOMETEXT
+   points to an .html file which is included on the gitweb project
+   overview page.
+ * GITWEB_CSS
+   Points to the location where you put gitweb.css on your web server.
