+TkPNG is an open source binary package that adds PNG photo image support to
+Tcl/Tk.  Although other extensions such as Img also add support for PNG
+images, this package was designed to be lightweight, not depending on libpng
+nor implementing other image formats, and suitable for inclusion in the Tk
+core.

+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|' on
+# the right side marks the last column you can put a character in.  You must make
+# exactly 11 lines for the formatting to be correct.  It's also customary to
+# leave one space after the ':'.
