** NES Rotate 13 - Line Letter Flipper **
(c) NES/Theo Van Dinter/Bill Smith 1993
This program was developed as Shareware by Nor'Easter Software which
is a small software programming group which mostly makes utilities for
Bulletin Boards, and other small utilities which don't already exist to do
something which we need done. Nor'Easter software is made up of:
Theo Van Dinter : Sysop of the GS Connection BBS (1)
William Smith : Sysop of the GS Connection BBS (2)
Lucas Ives : Co-Sysop of the GS Connection BBS

This program is actually a simplistic file encrypter. It will take a file,
and any Alphabetic character (A through Z, and a through z) and swap them
with the opposite character in the group. Picture this:
Group 1 ABCDEFGHIJKLM abcdefghijklm
Group 2 NOPQRSTUVWXYZ nopqrstuvwxyz
If the character in the file is in group 2 (let's say R), it is replaced
by the character above it in group 1 (E). Same in reverse: Character v
is replaced by character i. This is also the same upside-down: Character
D becomes Q, and j becomes w.
You may already be asking, why would I want this? Let's say for example, you
have a message to goto a friend through either a public BBS, or a network, and
it's not exactly "in good taste". (ie: it's not private, but some people in
the public wouldn't like it too much.) Throw this program over it, and the
message becomes garbled enough so people can't read it, but easy enough to
decode if you want to read it. The top of this document looks like this:

To run this program, you just need double the space of the file, on your
disk. The program will not check, so you must make sure you have the space,
or else you will lose the end of the file (equal in the number bytes of the
space you didn't have). (ie: file is 260k, you have 259k free, you lose 1k.)
As the file is being scanned through, the information is written to a temp
file (typically called nestemp.~$$), and at the completion of the scan, it
is "copied" over the original file. That is why you will lose the information,
because you don't have the original anymore.
For operational parameters, please run the program with no commandline
parameters. It is self-explanitory from there.
