LHarc 2.01c (optimized version)

**** Please don't distribute this program without documentation ! ****

This version of LHarc is based on the original LHarc 1.13c. My only changes
are bug-fixes, some improvements and of course, speed-optimization. Normal
1.13-compression is about 4 times as fast as the original atari-version.
The new 2.0-compression is about 30% as fast as the original. With this
2.x-version of LHarc, the brand new LHA and the old Larc-formats are 
fully supported.

LHarc.ttp contains some other files: MAN.ENG, this readme and PFXPAK.PRG.
If you rename LHarc.ttp into LHarc.lzh, you will be able to extract these 
files.

How to make a shorter version of LHarc to work with.

  - Copy LHarc.ttp and name it LHarc.lzh
  - Double-click LHarc.ttp and type "x -rmh" (without the quotations-marks).
	It will now extract MAN.ENG PFXPAK\PFXPAK.PRG PFXPAK\PFXREAD.ME,
	PFXPAK\REGISTER.ENG and LHarc.ttp
  - Open the PFXPAK-foler and start PFXPAK.PRG
  - Click [compression] and select LHarc.ttp. LHarc.ttp will have a size
    of about 26KB afterwards.
  - It will no longer be possible to read the readme using 
	p LHARC.TTP MAN.ENG

Remember: Do not distribute LHarc as a shortend version. This only causes
frustration to all who get it. They can make their own short versions!


************ Important note: ***************

 If you are extracting older archives, you MUST give the -k - switch.
 This tells LHarc that there are no extended headers to skip.

History:

  2.01h

    - Comments
    - Extended-Headers are supported (pathname, comment etc.)
     
  2.01e

    - Packing AFX:

 	- The temporary file is stored in the same folder. Any errors in
          renaming cause LHarc to stop.
        - Programs, LHarc and AFX-Files are skipped. To skip AFX-Files AFX  
          must not be active. The registered version will be turned off by
          LHarc (the unregistered can't be turned off).

  2.01d 

   - Uses a different startup-code for argv. Someone told me, the old one
     did not work properly.
   - Full support of AFX
   - Bug removed: Extended headers now are ALLWAYS skipped.
   - Bug removed: Some functions did not support -d

  2.01c
 
   - First english version of LHarc 2.x.
   - Fully support of extended headers. 
   - Extended headers caused LHarc sometimes to stop working.
   - New switch: -k 

  2.01a 
  
   - Uses ARGV
   - Speedup due to assembly-optimisations.

  2.00b

   - Now accepts archives with extended headers. It is now possible to 
     extract all MS-DOS-archives.
   - It now uses less memory.

  2.00a 
  
   - Sometimes, lharc made errors in calculating the codesize. This made
 	 the archiv unreadable.

  2.00

	- This experimental version was first able to decode and encode -lh5-
    - While decoding, the format is determinded automatically.
    - While encoding, -lh5- is used automatically. Old archives may be
	  produced giving the -o - switch.
    - New switch: -l  (Support of Larc)
    - New switch: -s  (Changes \ into /)

 1.13.20

	- Webb's and unix .lzh-archives are now correctly decoded. The format
      is determined automatically.
    - Calling Lharc without a command is the same as giving -rm. It is now
	  possible to install LHarc as an application and to decode .lzh with	
	  a doubleclick.
    - New flag: -u (Store without compression)

 All others:

	- Many speed-optimizations
    - LHarc accepts an "infite" number of files. The original accepted only
	  100
    - The -lz4- and -lz5-formats are now correctly accepted.
    - Changed "o" into "*"
	- The number of "*" now is proportional to the length of the file.
	- It is now possible to extract SFX and PFX
    - New switch: -y, -b.
    - Full buffering of files.
	- New switch: -d
