- WARNING!
- ========
-
- Please note! Unlike other, similar programs (LZEXE & PKLITE), DIET does
- *not* warn you if it encounters a program with "overlays." It simply
- compresses the file anyway.
-
- Sometimes, overlay data is superfluous (e.g., debugging code). If
- that's the case, the resulting compressed file will execute properly.
- BUT, if the original program contained overlays, DIET will *not* be able
- to "retrieve" an exact copy of the original using the -R option. The
- overlay data is gone for good.
-
- If the overlay data was needed -- as it very often is -- DIET will
- produce a compressed file that will not run properly *and* which can not
- be restored with the -R option. In short, your original is gone.
-
- Moral of the story: Backup any program on which you are going to run
- DIET. After you have done so, test the results in 2 ways:
-
- (1) Does the compressed file execute properly?
-
- (2) If you restore the compressed file using DIET -R, is the
- "retrieved" file identical to your backup copy? You can test this
- using the DOS COMP program or any similar utility.
-
- If you don't follow the above safeguards, good luck!

- This note created for the sake of callers to my BBS. I have no
- connection with the author of DIET, take no responsibility for the
- program and take no credit for it (I couldn't begin to write a program
- as sophisticated as this). I'm just a nervous Sysop <grin>.
