Signify is copyright (c) 1996-1998 by Verisim, Inc. and may be distributed
in its unmodified (i.e. "archive") form without restriction.  It may also
be distributed without fee in accompaniment of another product so long the
Signify program itself, this man page, and the basic examples (those
starting with a capital letter) are all included in their original,
unmodified state.

Signify may also be redistributed without restriction with any additions
or modifications so long as a copy of those changes (eg. a diff from the
original) are also emailed to signify-bugs@verisim.com so they can be
included in the "upstream version" and thus propogated to all users of
this software.

In addition, up to 25% of the Signify code may be included directly in
another product without requiring the express permission of Verisim,
Inc.
