===========================================================================

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.
