Remote helper programs are invoked with one or (optionally) two
arguments. The first argument specifies a remote repository as in git;
it is either the name of a configured remote or a URL. The second
-argument specifies a URL of the form '<transport>://<address>' or
-'<transport>::<address>', where '<address>' may be an arbitrary
-string.
+argument specifies a URL; it is usually of the form
+'<transport>://<address>', but any arbitrary string is possible.
When git encounters a URL of the form '<transport>://<address>', where
'<transport>' is a protocol that it cannot handle natively, it

If 'push' is supported this may be called as 'list for-push'
to obtain the current refs prior to sending one or more 'push'
commands to the helper.

'connect' <service>::
------------
'fetch'::
- This helper supports the 'fetch' command.
-
'option'::
- This helper supports the option command.
-
'push'::
- This helper supports the 'push' command.
-
'import'::
- This helper supports the 'import' command.
+'connect'::
+ This helper supports the corresponding command with the same name.
'refspec' 'spec'::
When using the import command, expect the source ref to have
all, it must cover all refs reported by the list command; if
it is not used, it is effectively "*:*"
-'connect'::
- This helper supports the 'connect' command.

'option verbosity' <N>::

+ Changes the verbosity of messages displayed by the helper.

If enabled the helper should automatically fetch annotated
helpers this only applies to the 'push', if supported.
