 DESCRIPTION

 A simple CGI program to serve the contents of a Git repository to Git
 clients accessing the repository over http:// and https:// protocols.

+The program supports clients fetching using both the smart HTTP protocol
 and the backwards-compatible dumb HTTP protocol, as well as clients
 pushing using the smart HTTP protocol.
 
+It verifies that the directory has the magic file
+"git-daemon-export-ok", and it will refuse to export any git directory
+that hasn't explicitly been marked for export this way (unless the
+GIT_HTTP_EXPORT_ALL environmental variable is set).
+
 By default, only the `upload-pack` service is enabled, which serves
-'git-fetch-pack' and 'git-ls-remote' clients, which are invoked from
-'git-fetch', 'git-pull', and 'git-clone'.  If the client is authenticated,
