usage: git cms-remote add [--ssh|--https] [-w|--enable-push] USER

Description:
  Adds a remote repository called USER pointing to https://github.com/USER/cmssw.git .
  By default only fetching from this remote is enabled, using the HTTPS protocol.
  The default behaviour is to immediately fetch the new remote repository; this can be
  disabled with the '--no-fetch' option.
  Pushing can be enabled with the '-w' or '--enable-push' option; the default is 
  to use the SSH protocol.
  If '--ssh' is given, the SSH protocol will be used for all URLs.
  If '--https' is given, the HTTPS protocol will be used for all URLS.

Options:
    -h|--help           display this usage message
    --https             use the HTTPS protocol for fetching and pushing
    --ssh               use the SSH protocol for fetching and pushing
    --fetch             automatically fetch the new remote (default)
    --no-fetch          do not automatically fetch the new remote
    -w|--enable-push    enable pushing to the new remote
