# The license for this stuff is yet to be written.

# Please don't do anything good with it without at

# Lenzo, lenzo@cs.cmu.edu), and the Carnegie Mellon

# Also, there is work being done on various bits of this

# now by various people; if you have any corrections

# or contributions, please send them to me. Flat
|

# ascii files of databases, made with dump_db, are

# wonderful things to share, and a repository will be
|
|
# set up.
