+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.
+ * GITWEB_LOGO
+   Points to the location where you put git-logo.png on your web server.
