- A high performance Data compression utility for the Commodore Amiga
- Amiga user interface and compression code by Stefan Boberg
- Original 80x86 LZHuf code by Haruyasu Yoshizaki
-
- PRE-RELEASE V0.99a
-
- ===========================================================================
-
- Ok, so here it is, the fully Intuitionized, FAST! LhArc compression tool
- for the Commodore Amiga, this is only a pre-release so there's no real
- documentation yet. It is 100% compatible with LhArc version 1.13c (MSDOS)
- and Amiga LhArc (The Italian CLI version), only it is MORE than TWICE as
- fast !!! I hope you will understand how to use it anyway, but here's some
- tips to get you going:
-
- EXTRACTING
-
- If you want to extract files from an existing archive, first select 'Open
- Archive' from the Project menu or press Right-Amiga+O or just press 'O'.
- Then select the file from the file requester by entering the source
- directory in the Dir gadget and then click twice on the file you want to
- extract from, or enter the file's name in the File gadget and press RETURN.
- Then click on the files you want to extract (clicking once selects,
- clicking a second time deselects again), or use the 'Mark all', 'UnMark
- all' and 'Mark...' gadgets. The 'Mark...' gadgets allow you to enter an
- ARP-pattern mask to select certain files. (For example. '*.c' will select
- all files ending in '.c' and 'a*z' will select all files that begin with an
- 'a' and end with a 'z', detailed explanations of the pattern matching
- functions will be in the final documentation). When you have marked
- (highlighted) all files you want to extract, click on the 'Extract' gadget.
- Now you will be asked where to put the extracted files, select a directory
- and click on the 'OK' gadget. Now LhArcA will extract your files! If you
- want LhArcA to consider extended filenames, select 'Extended filenames' in
- the Settings menu.
-
- CREATING AN ARCHIVE
-
- When you want to create a new archive, select 'New archive' in the Project
- menu, then enter the destination directory and archive name. NOTE: In
- this pre-release you must append '.lzh' after the filename, otherwise
- LhArcA cannot open it for extraction! This will be fixed in the final
- release. Then do just like you do when you add files to an existing
- archive. (Described below).
-
- ADDING FILES TO AN EXISTING ARCHIVE
-
- This is easy, first open the archive as when extracting (see above), then
- click on the 'Add files' gadget and then select the files you like to add.
- You can select as many files as you like and in as many directories you
- like. If you want pathnames to be stored, select 'Extended filenames' in
- the Settings menu and then set 'Home directory' to the part of the pathname
- that should not be stored. (Not enough space to describe this here, wait
- for the final version, it will probably work differently then).
-
- ADDITIONAL NOTES
-
- The final version, there will be all the features found in other archivers
- (including PkAZip), and more. LhArcA is FASTER than PkAZip!!! (About
- 15%), and also more effective. To make it even faster I am working on some
- new search algorithms which will (hopefully) be finished until the final
- release!!! Also in the final release there will be the option to issue
- archiver commands directly from the CLI command line (as Zoo, Arc, LhArc
- etc.), my intention is to make a program everybody can use, both novices
- and experts. (Though this version may be a little hard to understand, I
- will possibly add some online help stuff in the final version). Also it
- will be possible to create SFX-archives (self-extracting archives), and
- more....
-
- Anyway, if you have any ideas for improvements, or find any bugs (I have
- sorted out most of them now, there are (I hope) no serious bugs left, just
- some things that need to be more polished). Anyway hope you like this,
- because it took be two months to get this far!! If you like it, PLEASE
- consider sending me a contribution, look in the About... text for more
- details.

-
- SYSTEM REQUIREMENTS:
-
- You'll need:
-
- * Arp.library (Version 39.1 is included in this archive).
- * An Amiga with at least 512K of RAM.
- * You must have ASSIGNed 't:' somewhere. (Preferably to RAM:, to do this,
- enter the command 'ASSIGN t: ram:' before running LhArcA.
-
- INSTALLING
-
- To install LhArcA, extract the files from this archive, then execute the
- following commands from CLI:
-
- copy Arp.library to libs:
- delete Arp.library
-
- This will move the Arp.library to where it should be.
