-----------------------------------------------------------------
 running the program
-----------------------------------------------------------------
When the program is compiled, you can run it without any arguments:

  % p4

-----------------------------------------------------------------
 compiling: Linux and Mac OS X
-----------------------------------------------------------------
To compile:

On Linux or Mac OS X, define the following environment variables.
(Use export for bash, setenv for tcsh and csh).

Linux:
  export ARCH=linux

Mac OS X:
  export ARCH=macosx

Either:
  export JOT_ROOT=/path/to/your/jot/install

If you are using CAEN linux, the path to precompiled jot is:

  /afs/engin.umich.edu/class/perm/eecs487/jot

Then you should be able to build the project by typing 'make'.
(No need to edit the Makefile.)

-----------------------------------------------------------------
 compiling: Windows
-----------------------------------------------------------------
On Windows, you have to compile using a DOS shell, but can
use cygwin or DOS for running p4.

If using the pre-compiled jot libraries on CAEN, ensure that
/afs/engin.umich.edu/class/perm/eecs487/ is accessible; do this
by mapping a networked drive:

Start menu --> My Computer --> Tools --> "Map Network Drive"

Choose a letter for the drive (e.g. Z:)
Enter the folder: \\afs\engin.umich.edu\class\perm\eecs487

-----------------------------------------------------------------
Edit proj4/setup.bat according to the instructions (look for 'XXX').
You need to define JOT_ROOT and the path to your proj4 directory
(and VSYEAR if not using Visual Studio 8).

Note that in setup.bat, slashes go backward:

set JOT_ROOT=Z:\jot

If you are using Visual Studio 2003, you will also need to change:

set VSYEAR=2005

to:

set VSYEAR=2003

-----------------------------------------------------------------
Also edit the Makefile to define JOT_ROOT (in the WIN32 section).
Note slashes go forward in the Makefile:

JOT_ROOT = Z:/jot

-----------------------------------------------------------------
On your desktop, create a shortcut for launching a DOS shell with
environment variables set for compiling p4:

E.g., if your proj4 directory is H:\Private\proj4, 
the shortcut should have the following target:

  %SystemRoot%\system32\cmd.exe /k H:\Private\proj4\setup.bat

Give the shortcut a reasonable name, e.g.: 'proj4'

Double click the shortcut to start a DOS shell.
In that shell, type "make" -- the project should compile!
