T-Undo
Version 1.0
Written by Todd M. Kennedy, 1992.
What is T-Undo?
While searching the archives on Internet, I found a very interesting
program by the name of 'undo'. This program would take (almost) any compressed
file, track down the archiver, and then procede to de-archive it.
Unfortunately, the program was cripple-ware unless you sent in your $20
share-ware fee. Well, I didn't like the idea, and thus, T-Undo was born.
T-Undo is much like it's predecessor, but, with some key differences. First,
there is basically no limit to the number of types of files it will undo.
(However, I set a max of 25 types on this version. It can be expanded if
anyone ever hits that limit) And, there is no shareware fee for the full
version. What you see here, is everything you get.
What you need to use T-Undo
T-Undo requires a configuration file for normal operation. One has been
supplied with the archive, and it should be enough to get you started. The
configuration file can be placed either in the directory you do you
de-arciving from, or, somewhere along your path. It T-Undo can't find it,
it will let you know!
Other than the configuration file, T-Undo only requires you to have the
various de-archivers specified in the configuration file.
How to use T-Undo
The format for the command-line is:
tundo [/c] [/v] archive_Name [fileName [fileName [filename [...]]]]
/c -- prints out how T-Undo sees your configuration file. Great for
debugging if something isn't being setup correctly.
/v -- only views the contents of archive_Name and does not
de-compress it.
archive_Name -- the name of the archive you want to decompress or
view. It can be any valid filename with or without
wildcards.
fileName -- any valid name that is contained in archive_Name. This
is usefull for partial decompression. fileName can also
have wildcards.
If you run T-Undo with no arguments, the help line is printed out. More
extensive help is planned for further versions.

How to setup the configuration file
The configuration file is quite simple to setup. First, start out with the
extension in square brackets. (i.e. [.ZIP], [.zIp], and [.zip] are all the
same) The next line should be the name of the unarching program. (Such as
pkunzip, lharc, etc...) If you don't specify and exact pathname, T-Undo will
automatically search your environment's PATH= statement. The next line are
the parameters required to un-compress the file. (This is needed for lharc,
dwc, and others) The last line contains the parameters required to view the
archive. If you do not want to specify any parameters for either viewing or
decompressing, simply use the word "NULL". (In all uppercase) The config file
contained in this archive should be helpful in setting up other config entries.
NOTE: It is possible for you to use T-Undo for more than compressed files.
For instance, you can use this config to edit all your .doc files
with the popular QEdit program.

Where to reach the author
I am VERY open to opinions. (After all, I developed the program for my
needs, and am sure that other users have different needs) Also, if any bugs
are found, I would like to know about them in order to squash 'em dead! So,
with that aside, you can reach me through EMail at:
tkennedy@hypnos.CalPoly.EDU
or
tkennedy@polyslo.CalPoly.EDU
or, if you don't have access to EMail, I can be reached via snail mail at:

NOTE: I am a student at Cal Poly State U, and do NOT reside in San Jose.
Any mail sent there will be forwarded by my father, and so, response
will be relatively slow.
NOTE: If you want to use the above address to send money, be more than
welcome to. However, please remember, this is a free program, and no
money is needed to feel guilt-free about using it! But, if you DO use
it, a quick note or letter would be appreciated.
