    """Qt-based GUI Commit Tool
    
       This command will open a window from which you
       can browse all of the pending changes you have made
       to your branch.  You can then type in a commit log
       message and commit your changes to the repository.
       You can remove files from the commit list by de-selecting
       them in the file list.

       Keyboard Shortcuts:

       CTRL-O  - Commit selected files
       CTRL-R  - Refresh file list
       CTRL-N  - View diffs of next file in list
       CTRL-[] - Page up/down through file diffs
       CTRL-U  - Unselect all files
       CTRL-F  - Clear file filter text
       ESC     - Abort and exit
