+# This file is a Tcl script to test out the procedures in tkUnixFont.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. Some tests depend on the
+# fonts having or not having certain properties, which may not be valid
+# at all sites.
