PMdiff version 3.1 release notes (1st July 1995)

For IBM OS/2** Warp 3.0, Microsoft Windows NT** 3.5, and 
Windows 95**. PMdiff 3.1 will _NOT_ run on OS/2 2.x or Windows 
NT 3.1.

________________________________________________________________
INTRODUCTION

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.

PMdiff is available for IBM OS/2 Warp version 3.0, Microsoft 
Windows NT 3.5, 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

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).
