- What is DIET?
- =============
- DIET compresses executable files with DLV-method, dynamic Lempel-Ziv,
- into executable files preserving the file names. The method of compression
- is similar to Lexem093.exe with @ switch.
- You can create exe or com files in compressed size with a
- decompression so fast that you would feel as if you are working with the
- uncompressed original. DIET is similar to LZEXE or PKLITE in concepts
- and is an outgrowth of LEXEM which has gained much popularity in Japan.
- Some of the new features of DIET are:
-
- *DIET accepts wild cards:
- Type DIET *.* whenever your storage space causes you a panic.
-
- *DIET uses the same name for a compressed file, and overwrites the original
- on default.
-
- *DIET retrieves the original with the same attributes and time stamp.
-
- *DIET compresses ASCII files, too.
-
- *DIET can change the original name into another name with -o option.
- You may save the original file with this facility.
-
- *DIET uses new file header which decreases the compressed file size.
-
- *DIET uses only a small portion of available memory in decompression.
- Its size is far smaller than LEXEM uses.

- Effective Use of Diet.
- ======================
- What is more comfortable than to type
- DIET *.*
- while similar utilities ask you one command line to compress each file?
- You may just type
- DIET -r *.*
- to restore all the files into the original sizes. You may restore
- only some of the data files by:
- DIET -r *.dat
- DIET -r *.log
- DIET -r *.pif
- and so on. And keep all of your executable files in compressed size.
- This utility has minimum amount of switches and commands to go
- with Diet. You do not have to read lengthy manual or documents.
- Our document itself is compact as your Laptop.
-
- Diet overwrites every file which it compresses, and removes the
- original. The compressed file is stored where the original was.
- Try to take directory before and after it compressed every thing.
- You just get the same list of files in the same order, neat and tidy.
-
-
- <<< Usage >>>
-
- Usage : DIET [option] filename [filename]...
- Option: -C check already compressed
- -R retrieve original file
- -Oxxxx output file is xxxx.
-
- This is all what you have to remember with its capability for
- accepting wild cards. Parameters in angle braces [....] may be
- omitted. For an example,
-
- DIET \bin\format.com
-
- will produce the following message:
- ..
- <<<< executable file compressor DIET ver 1.00 >>>>
- ... copyright 1990 Teddy Matsumoto ...
-
- Compress '\BIN\FORMAT.COM' .Success! (10208 to 6889 bytes)
-
-
- The compressed file format.com is in the directory \bin.
- To retrieve the original type:
-
- DIET -r \bin\format.com
-
- What you see is the information:
-
- <<<< executable file compressor DIET ver 1.00 >>>>
- ... copyright 1990 Teddy Matsumoto ...
-
- Retrieve original file '\BIN\FORMAT.COM'
- Success! (6889 to 10208 bytes)
-
-
- Throghout the process of compression and decompression, the time stamp
- of the file remains the same.
-
- To check whether some of your files are compressed by DIET use c option.
-
- DIET -c \bin\*.*
-
- Then you see something like:
-
- <<<< executable file compressor DIET ver 1.00 >>>>
- ... copyright 1990 Teddy Matsumoto ...
-
- '\BIN\LHARC.EXE' is already compressed by DIET!
- (packed data size: 20118 bytes CRC: 0B4B)
- '\BIN\LESS.EXE' is not compressed by DIET!
- '\BIN\LESS.HLP' is already compressed by DIET!
- (packed data size: 400 bytes CRC: 0572)
- '\BIN\SYS.EXE' is already compressed by DIET!
- (packed data size: 2394 bytes CRC: 3190)
- '\BIN\SED.EXE' is already compressed by DIET!
- (packed data size: 14057 bytes CRC: F77B)
- '\BIN\LINK.EXE' is not compressed by DIET!
- '\BIN\SORT.EXE' is already compressed by DIET!
- (packed data size: 928 bytes CRC: 0B71)
- '\BIN\TEE.COM' is already compressed by DIET!
- (packed data size: 7390 bytes CRC: 79D4)
- '\BIN\TREE.COM' is already compressed by DIET!
- (packed data size: 1245 bytes CRC: A1CC)
- '\BIN\DIET.EXE' is not compressed by DIET!
- '\BIN\FGREP.EXE' is already compressed by DIET!
- (packed data size: 9024 bytes CRC: 5C27)
- '\BIN\PKLITE.EXE' is not compressed by DIET!
-
-
- Finally, to change output filename you type
-
- DIET -O\bin\lh.exe \bin\lharc.exe
-
- Follwing information is supplied by DIET:
- .......
- <<<< executable file compressor DIET ver 1.00 >>>>
- ... copyright 1990 Teddy Matsumoto ...
-
- Compress '\BIN\LHARC.EXE' to '\bin\lh.exe' .Success! (31256 to 20409 bytes)
-
- To see what has happened look the directory:
-
- dir \bin\lh*
-
- LHARC EXE 31256 89-05-21 21:14
- LH EXE 20409 90-12-23 17:32.
-
-
- Note that the original file is not overwritten and is kept there.
-
- DIET -r \bin\lh.exe
-
- <<<< executable file compressor DIET ver 1.00 >>>>
- ... copyright 1990 Teddy Matsumoto ...
-
- Retrieve original file '\BIN\LH.EXE'
- Success! (20409 to 31256 bytes)
-
-
- dir \bin\lh*
- ------------
-
- LHARC EXE 31256 89-05-21 21:14
- LH EXE 31256 90-12-23 17:32
-
-
- You must know the time stamp of lh.exe has been changed, but not the
- original lharc.exe's. You can keep the original file if you want to
- take some precaustions.
