+;;; Commentary:
+
+;; An implementation of information caching for remote files.
+
+;; Each connection, identified by a vector [method user host
+;; localname] or by a process, has a unique cache. We distinguish 3
+;; kind of caches, depending on the key:
+;;
+;; - localname is NIL.  This are reusable properties.  Examples:
+;;   "remote-shell" identifies the POSIX shell to be called on the
+;;   remote host, or "perl" is the command to be called on the remote
+;;   host, when starting a Perl script.  These properties are saved in
+;;   the file `tramp-persistency-file-name'.
+;;
+;; - localname is a string.  This are temporary properties, which are
+;;   related to the file localname is referring to.  Examples:
+;;   "file-exists-p" is t or nile, depending on the file existence, or
+;;   "file-attributes" caches the result of the function
+;;  `file-attributes'.
+;;
+;; - The key is a process.  This are temporary properties related to
+;;   an open connection.  Examples: "scripts" keeps shell script
+;;   definitions already sent to the remote shell, "last-cmd-time" is
+;;   the time stamp a command has been sent to the remote process.
+

+
+;; Pacify byte-compiler.

+
+;; Access functions for FIles transferred over SHell protocol from Tramp.
+
+;; FISH is a protocol developped for the GNU Midnight Commander
+;; <https://savannah.gnu.org/projects/mc>.  A client connects to a
+;; remote host via ssh (or rsh, shall be configurable), and starts
+;; there a fish server via the command "start_fish_server".  All
+;; commands from the client have the form "#FISH_COMMAND\n" (always
+;; one line), followed by equivalent shell commands in case there is
+;; no fish server running.
+
+;; The fish server (or the equivalent shell commands) must return the
+;; response, which is finished by a line "### xxx  <optional text>\n".
+;; "xxx" stands for 3 digits, representing a return code.  Return
+;; codes "# 000" and "# 001" are reserved for fallback implementation
+;; with native shell commands; they are not used inside the server.  See
+;; <http://cvs.savannah.gnu.org/viewcvs/mc/vfs/README.fish?root=mc&view=markup>
+;; for details of original specification.
+
+;; The GNU Midnight Commander implements the original fish protocol
+;; version 0.0.2.  The KDE Konqueror has its own implementation, which
+;; can be found at
+;; <http://websvn.kde.org/branches/KDE/3.5/kdebase/kioslave/fish>.  It
+;; implements an extended protocol version 0.0.3.  Additionally, it
+;; provides a fish server implementation in Perl (which is the only
+;; implementation I've heard of).  The following command reference is
+;; based on that implementation.
+
+;; All commands return either "### 2xx\n" (OK) or "### 5xx <optional text>\n"
+;; (NOK).  Return codes are mentioned only if they are different from this.
+;; Spaces in any parameter must be escaped by "\ ".
