# This file is a Tcl script to test out the procedures in tkWinFont.c.
# It is organized in the standard fashion for Tcl tests.
#
# Many of these tests are visually oriented and cannot be checked
# programmatically (such as "does an underlined font appear to be
# underlined?"); these tests attempt to exercise the code in question,
# but there are no results that can be checked.
