In order to run the Leech Tutorial described in Chapter 10, and contained
in the calabrese directory of this CDROM, you need a customized version of
GENESIS that contains additional objects that are used by the tutorial.

If you are using Linux, Solaris, or IRIX 6, you may use one of the precompiled
genesis binaries. These have the necessary leech libraries compiled in.
Otherwise, follow these steps:

(1) Compile and install genesis by following the directions under
"Installation using the archived distribution" in the README file.

(2) Copy the leech-genesis directory (or extract leech-genesis.tar.Z) to your
hard drive.

(3) Follow the directions in leech-genesis/README to create the modified
version of GENESIS "lgenesis".

(4) The Leech Tutorial and instructions for running it are contained in the
calabrese directory on this CDROM.  It may be best to copy the entire
calabrese/leech-tutorial directory to your hard drive to run the tutorial.
You can then copy lgenesis to the leech-tutorial directory to run the
tutorial.

NOTE:  In some versions of leech-tutorial, the file tutorial.g may
have a line near the beginning with a "hard-coded" pathname, such as

    str file_prefix = "/home/rcc/cnrme/Calabrese/leech-tutorial"

You will either need to change this to the path to your copy of
leech-tutorial, or to the general statement:

   str file_prefix = {getenv PWD}
