ftp://user:password@host:port/file
file://user:password@host:port/file
These schemes are defined in RFC 1808. ‘ftp:’ and ‘file:’ are synonymous in this library. They allow reading arbitrary files from hosts. Either ‘ange-ftp’ (Emacs) or ‘efs’ (XEmacs) is used to retrieve them from remote hosts. Local files are accessed directly.
Compressed files are handled, but support is hard-coded so
that jka-compr-compression-info-list and so on have
no affect. Suffixes recognized are ‘.z’, ‘.gz’, ‘.Z’ and ‘.bz2’.
