+% This is the source file for blackboard.ps .
+% blackboard.ps is supposed to help you choose the
+% appropriate blackboard bold font for your document.
+%
+% Unless you intend to change this file (which is perfectly ok)
+% you should probably get blackboard.ps directly.
+% It should be on the ftp site where you got this file from.
+% That will save you installing all the fonts.
+%
+% This file is in the public domain. You may do everything
+% with it, including, but not limited to, printing it
+% and folding paper planes with the results.
+%
+% This file is unsupported. If you want to support it, go ahead.

+This is a test file for the various implementations of
+blackboard bold typefaces in \TeX.
+It was written by Olaf Kummer during July 1998.
+It is unsupported.
+
+Using this file you can preview the different fonts
+in a postscript file without actually installing all the
+fonts. This might help you in choosing a font that is
+most appropriate for your task.
+The author has prepared a blackboard bold font himself,
+but he hopes that this file shows as little prejudice as
+possible.
+
+{\tt testfont.tex} was used to prepare the font tables
+in this document.
