License Text

  % This is a package of commutative diagram macros built on top of Xy-pic%
  % by Michael Barr (email:  barr@barrs.org).  Its use is unrestricted.  It%
  % may be freely distributed, unchanged, for non-commercial or commercial%
  % use.  If changed, it must be renamed.  Inclusion in a commercial%
  % software package is also permitted, but I would appreciate receiving a%
  % free copy for my personal examination and use.  There are no guarantees%
  % that this package is good for anything.  I have tested it with LaTeX 2e,%
  % LaTeX 2.09 and Plain TeX.  Although I know of no reason it will not work%
  % with AMSTeX, I have not tested it.%
