;; This function bypasses the file name handler approach. It is NOT
;; recommended to use it in any package if not absolutely necessary,
;; because it won't work for remote file names not supported by Tramp.
;; However, it is more performant than `file-local-name', and might be
;; useful where performance matters, like in operations over a bulk
;; list of file names.

This function removes from NAME the specification of the remote
host and the method of accessing the host, leaving only the part
that identifies NAME locally on the remote system. NAME must be
a string that matches `tramp-file-name-regexp'. The returned
file name can be used directly as argument of ‘process-file’,
‘start-file-process’, or ‘shell-command’."
