# Release Notes

# fixed bug for string wider than print region
# add index to data list after parsing total pages for paging
#----------------------------------------------------------------------------
# 12/10/2003 - Jeff Grimmett (grimmtooth@softhome.net)
# o 2.5 compatability update.
#----------------------------------------------------------------------------
# 11/23/2004 - Vernon Cole (wnvcole@peppermillcas.com)
# o Generalize for non-2-dimensional sequences and non-text data
#   (can use as a simple text printer by supplying a list of strings.)
# o Add a small _main_ for self test
