BRIEF:
In-place (non-filter) encoding/decoding of ASCII files, using
an interactively acquired key, or the value of the environment
variable MIXKEY, or one constructed from user's effective user id.
Shuffles the bytes of the file; the retained character set
permits ASCII file transfers. Provides the key holder immediate
access (vi, grep, make, etc.) to scrambled files such that the
scrambled nature of the files is transparent. The objects
edmix, keymix, unmix, catmix are links of mix, argv[0] is
hashed to decode context.
