To install:

1. Move t to a directory in your shell's path.  For example,
we put t in "/usr/local/bin".

2. Create a tsystem directory and set the environment variable 
TSYSTEM to the path name of the directory.
For example, our TSYSTEM is "/usr/local/lib/tsystem".
Add the definition of TSYSTEM to your login script so it will
be defined whenever you use t.

3. Copy the files in this directory into the T system directory. 

4. Perform "make" in $TSYSTEM to make the tsystem binaries and scripts.

To make T from sources:

1. Make xt.o on a Sun3.

2. Convert xt.o to Mach-O format with "atom xt.o t.o".

3. Link using the command "$TSYSTEM/linkt t t.o".
