These are some of the things that need to be done to make cybercash
work:

1. Copy over an mck directory of the right type (there is one for
   Solaris in /home/jsc/mck-3.2.0.2-solaris-sparc on xolas8).

2. Copy over a cybercash module directory (there is one in
   /home/jsc/cybercash, xolas8).

3. Get a merchant_conf file for the proper merchant (there is one for 
   ArsDigita in /home/cybercash/mck-cgi/conf/merchant_conf).

3. Edit the variables at the top of the cybercash module Makefile.

4. type make; copy the resulting cybercash.so to /home/nsadmin/bin

5. add "cybercash=cybercash.so" to the ns/servername/modules section of
   your server.

Note: I had to also change the merchant_conf directory in
cybercash.c, even though it was defined in the Makefile, otherwise
I got an error in the AOLserver logs.
