-;;; Commentary:
-
-;;; This package implements low-level support for reading, writing,
-;;; and loading compressed files. It hooks into the low-level file
-;;; I/O functions (including write-region and insert-file-contents) so
-;;; that they automatically compress or uncompress a file if the file
-;;; appears to need it (based on the extension of the file name).
-;;; Packages like Rmail, VM, GNUS, and Info should be able to work
-;;; with compressed files without modification.
-
-
-;;; INSTRUCTIONS:
-;;;
-;;; To use jka-compr, simply load this package, and edit as usual.
-;;; Its operation should be transparent to the user (except for
-;;; messages appearing when a file is being compressed or
-;;; uncompressed).
-;;;
-;;; The variable, jka-compr-compression-info-list can be used to
-;;; customize jka-compr to work with other compression programs.
-;;; The default value of this variable allows jka-compr to work with
-;;; Unix compress and gzip.
-;;;
-;;; If you are concerned about the stderr output of gzip and other
-;;; compression/decompression programs showing up in your buffers, you
-;;; should set the discard-error flag in the compression-info-list.
-;;; This will cause the stderr of all programs to be discarded.
-;;; However, it also causes emacs to call compression/uncompression
-;;; programs through a shell (which is specified by jka-compr-shell).
-;;; This may be a drag if, on your system, starting up a shell is
-;;; slow.
-;;;
-;;; If you don't want messages about compressing and decompressing
-;;; to show up in the echo area, you can set the compress-name and
-;;; decompress-name fields of the jka-compr-compression-info-list to
-;;; nil.
-
-
-;;; APPLICATION NOTES:
-;;;
-;;; rmail, vm, gnus, etc.
-;;; To use compressed mail folders, .newsrc files, etc., you need
-;;; only compress the file. Since jka-compr searches for .gz
-;;; versions of the files it's finding, you need not change
-;;; variables within rmail, gnus, etc.
-;;;
-;;;
-;;; crypt++
-;;; jka-compr can coexist with crpyt++ if you take all the decompression
-;;; entries out of the crypt-encoding-list. Clearly problems will arise if
-;;; you have two programs trying to compress/decompress files. jka-compr
-;;; will not "work with" crypt++ in the following sense: you won't be able to
-;;; decode encrypted compressed files--that is, files that have been
-;;; compressed then encrypted (in that order). Theoretically, crypt++ and
-;;; jka-compr could properly handle a file that has been encrypted then
-;;; compressed, but there is little point in trying to compress an encrypted
-;;; file.
-;;;
-;;;
-;;; tar-mode
-;;; Some people like to use extensions like .trz for compressed tar files.
-;;; To handle these sorts of files, you have to add an entry to
-;;; jka-compr-compression-info-list that looks something like this:
-;;;
-;;; ["\\.trz\\'" "\037\213"
-;;; "zip" "gzip" nil ("-q")
-;;; "unzip" "gzip" nil ("-q" "-d")
-;;; t
-;;; nil]
-;;;
-;;; The last nil in the vector (the "extension" field) prevents jka-compr
-;;; from attempting to add .trz to an ordinary file name when it is looking
-;;; for a compressed version of that file (i.e. don't look for things like
-;;; foobar.c.trz).
-;;;
-;;; Finally, to make tar-mode start up automatically, you have to add an
-;;; entry to auto-mode-alist that looks like this
-;;;
-;;; ("\\.trz\\'" . tar-mode)
