NT 3.1.
The Windows NT**/Windows 95** version of PMdiff has not yet been

E-mail arac@demon.co.uk for further details.
You can now order PMdiff by credit card! See orderfrm.txt for
more information.
________________________________________________________________
INTRODUCTION
Araxis PMdiff is a graphical file comparison application. It
works the way you work. Visually. Files are displayed side by
side. Differences are highlighted and lines are drawn showing
how the files are related.
PMdiff allows you to select text from two versions of a file
and produce a new version containing just the changes you want.
The Windows NT version of PMdiff 3.1 enables you to compare
directory structures and the files within them, quickly and
easily.
PMdiff for OS/2 is fully integrated with OS/2's Workplace
Shell. To compare files, simply drag and drop them onto the
PMdiff object, or onto the running application.
PMdiff is highly configurable. Fonts and colours and other
settings can be altered to show changes in a way that suits
you. Check the friendly on-line help for details.
PMdiff makes full use of OS/2 and NT's advanced features.
Such as notebooks and pop-up menus (via mouse button two).
PMdiff is an excellent addition to any OS/2 or NT software
development product. See 'Licensing PMdiff' in the on-line
help for details of how to bundle PMdiff with your
leading-edge system.
Araxis PMdiff is available for IBM OS/2 Warp version 3.0,
Microsoft Windows NT 3.51, and Windows 95.
________________________________________________________________
INSTALLATION
Run the friendly installation program (instos2.exe for OS/2 or
setup.exe for NT and Windows 95) supplied with the package. You
can install from floppy or hard disk. You may also use the Add
Programs icon in the Windows 95 Control Panel to install PMdiff
(Start->Settings->Control Panel->Add/Remove Programs).
Should you wish to uninstall the OS/2 version of PMdiff, simply
run the uninstallation program, uninst.cmd. You may manually
uninstall the NT version by deleting the contents of the PMdiff
installation directory and then the PMdiff 3.1 group in Program
Manager.
________________________________________________________________
GENERAL NOTES
Araxis PMdiff for OS/2 makes extensive use of drag and drop. Use
it to load files or change colours and fonts. Experiment with
the second mouse button. It activates a pop-up menu containing
many useful short-cuts.
The on-line help is comprehensive, although not all items are
available from General Help. Check out the Help Index to make
sure that you don't miss anything.
Two pairs of sample files are provided:
hippo1.txt, hippo2.txt
and mary1.txt, mary2.txt
You may wish to try comparing these.

EVALUATION VERSION
PMdiff is the result of many months of dedicated development
effort. It exists in evaluation and licensed versions.
The two version are identical, except that the evaluation
version does not allow preferences to be saved, won't save
merged files and pops up messages from time to time reminding
you of the benefits of registering. You may distribute the
evaluation version freely, and use it for up to 21 days.
If you find it useful then you are asked to register
it. This won't cost you much, and will gain you
* a disk containing the latest licensed versions (for
both OS/2 and NT) allowing preferences and merged
files to be saved
* free support via e-mail
* the satisfaction of supporting good OS/2 and NT software
* a clean conscience
See 'How to register and receive support' in the on-line help
for details about registration. You may like to use the text
file orderfrm.txt to help you place your order.
________________________________________________________________
LICENSED VERSION
The licensed version of PMdiff allows you to save your
preferences between sessions and save merged files.
This is to reward you for registering PMdiff.
You may install the licensed version on several machines.
However, you must ensure that only the number of copies
purchased are in use at any given time. You may use _either_
the OS/2 _or_ the NT version at a time, not both simultaneously
(unless, of course, you have purchased two or more licences).
For example, perhaps you have bought only one copy. You can
install it on your desktop office machine, and your laptop. Even
your home machine. But PMdiff must be run on only one of the
machines at any given time.

WARRANTY
Your attention is drawn to the disclaimer in the on-line help
(see 'Disclaimer' in the help index).

HISTORY
PMdiff 4.0 Fixed hang when PMdiff minimized. Fixed intermittent
operation of mouse actions on the left file.
PMdiff no longer stores the window position if
closed when minimized. Reduced frequency of messages
requesting registration. Fixed tab expansion
problem. Increased message queue length so that
processing of command line arguments works even
if certain software (such as Stardock's Object
Desktop) is installed which posts extra messages to
applications as they start. Removed PMdiff tribble
from product information dialog (R.I.P.), and
replaced with the shiny new Araxis PMdiff logo.
Added quick start help screen for new users.
CR and LF characters at the ends of lines are now
considered to be whitespace when doing whitespace
insensitive comparisons (hence you can't view trailing
CR/LF characters when ignoring whitespace).
If you find any faults in this version, let us know
because we've fixed everything reported so far.
PMdiff 3.1 Fixed several faults introduced in 3.0, and some
existing faults that surfaced during extensive
stress testing.
PMdiff 3.0 All known outstanding faults fixed. Go to
next/previous difference buttons, keyboard support
and file merge capability added. Also, optional
display of CR/LF characters and line numbers.
Icon updated. Tribble has experimented with
eye-shadow.
First port to Windows NT 3.5 and Windows 95. The
OS/2 version is for OS/2 Warp 3.0 and higher only.
It will not run on OS/2 2.x.
PMdiff 2.9 Internal version. Ported to IBM VisualAge C++
for OS/2 v3.0 from Borland C++ for OS/2 v1.5.
PMdiff 2.8 Internal version. Fault fixes and minor
enhancements.
PMdiff 2.7 Install program fixed (v2.6 install didn't work).
Uninstall script uninst.cmd added.
PMdiff 2.6 Minor bug fixes. Install program modified to create
a 'PMdiff' object rather than a 'PMDiff' one.
Registered versions sent to some beta testers.
PMdiff 2.5 First publically released version.
Install program added.
PMdiff 2.4 Beta-test version. Limited release.
PMdiff 1.0 Alpha version. Ported to Borland C++ for OS/2 1.0
(initial development was performed using the EMX
version of GNU gcc).
