+Description:  Modifies registry file (usually ~/.mplayer/registry)
+
+Usage:        modify_reg -r <registry_file> -l
+              modify_reg -r <registry_file> -k <key> [-d|-v <value>[-t <type>]]
+              -r|--registry - path to registry file
+              -l|--list     - shows all keys and values
+              -k|--key      - registry key
+              -d|--del      - delete key
+              -v|--value    - new value for key
+              -t|--type     - key type: string (default) or dword
