** UNRARWIN 1.0 **
Extended help file to include hypergraphics
Altered RENAME behaviour so that you cannot extract without altering
the target file name to one which does not already exist. This should
prevent Rename being clicked hastily without specifying a new file
name.
Latest version of Quickwin libraries used to give access to Help via
F1 key and menu option even when processing has terminated.

** UNRARWIN 0.9 beta **
96-03-23 Program renamed to UNRARWIN to match distribution network magic
name. Two changes:-
1) ? button added to invoke help.
2) Flags added to command line options (previously only available
when running interactively).
These changes are recent, and may thus be buggy. The flag options are not
the same as for the DOS UNRAR. A dump from the help file follows:-
Command Line
(using UNRARWIN like a DOS program)
Although UNRARWIN is really intended to be used interactively you can treat it like a DOS program and
give it command line arguments. The usage is similar, though not identical, to the standard DOS version.
UNRARWIN [command] [-flag] archive [extraction list]
command can be one of:-
E extract to current directory
X extract using stored pathnames
T test archive integrity
L list archive contents
V verbose listing of archive contents
(default X)
flag can be one of:-
R rename conflicting files
O overwrite conflicting files
U update conflicting files (overwrite if newer)
P preserve conflicting files (opposite of O)
(default -R)
The extraction list is a series of (optionally wildcarded) filenames which are to be extracted. The default is
ALL.
** WUNRAR 0.31 beta **
96-03-06 Corrected silly little bug that caused ".Enn" to be requested
instead of ".Rnn" when extracting from multi-volume SFX's.
** WUNRAR 0.3 beta **
96-02-25 Decided that searching for marker header in files with large
SFX stubs was messy and unecessary. Now merely perform a skip to end of
.exe file as indicated in header, and expect marker header to be appended
directly there. Seems to work OK!
***
Should now be able to process SFX files as well as normal archives. EXE
files are automatically identified by the initial "MZ" and the marker
header is then located and used to set the file position before normal
header analysis. File selection dialogue modified to include SFX files
as explicit option.

** WUNRAR 0.2 beta **
96-02-23 Corrected bug in unpack code which caused apparent CRC errors
for later members in very large archives (the freeware source had a typo).
***
This now has a functionality much closer to that which one would expect
from an UNRAR. The flag options are currently not supported from command
line. Explicit specification of target extraction directory has been added
since under Win 3.x current working directory is switched when you use a
file selection dialogue. There is still no help or documentation.

** WUNRAR 0.1 beta **
This is a quick and dirty port of the freeware UNRAR to Win 3.1. When arguments
are given it should behave very much as the DOS UNRAR does. For straight
expansion without frills WUNRAR will close when completed; if a listing option
is given or there are problems then the child window will remain until the
system close ('-' at upper left) is used.
If no arguments are given then a dialog box is invoked. Currently the flags
specification is disabled, since the freeware UNRAR code does not appear to
support them and I shall have to enhance it, and the ability to specify
individual files for extraction is also disabled, since I feel that a
multi-selection list box filled from the archive content might be more
appropriate here.
Since there is now a pucka WINRAR beta I suspect that WUNRAR should not be too
sophisticated. What do you think? This is a *very* early beta.

Note:- technically WUNRAR uses the MSC8 QuickWin Libraries modified to allow
API calls. This makes the .exe larger than it might be since it carries some
unecessary menu & MDI code with it, but provides an excellent framework for
'windozing' conventional C programs.
Unfortunately I cannot distribute these modified libraries, and so there is
little point in making the source code for WUNRAR available.
