+Subject: URW++ making original 35 fonts available under LPPL
+
+I am forwarding the message below on behalf of Peter Rosenfeld, Managing
+Director of URW++, who has kindly agreed to make the basic 35 PostScript
+fonts also available under the LPPL.  At his request, I'll be
+disseminating the information throughout the TeX community.
+
+Many thanks to Dr. Rosenfeld!
+
+Many thanks are also due to Karl Berry, TUG President, for his unswerving
+support and advice and Bogus\{}aw Jackowski, lead TeX Gyre developer,
+for pushing the issue.
+
+Best,
+Jerzy

+Subject: URW++ original 35 fonts available under LPPL
+
+To whom it may concern,
+
+Many years ago, URW++ Design and Development Inc. released their
+Type 1 implementations of the basic 35 PostScript fonts under the
+GNU General Public License and the Aladdin Ghostscript Free Public
+License.
+
+We now additionally release them under the LaTeX Project Public License
+(http://www.latex-project.org/lppl), either version 1 or (at your
+option) any later version.
+
+Of course, this additional licensing applies to the original URW++
+material, not any subsequent changes and additions made by other
+parties.
+
+The original font files are widely available, for instance as part of
+the Ghostscript 4.00 release, and therefore we are not releasing any new
+font files.  Those interested can replace the license terms in those
+original files accordingly.  Responsibility for ensuring that no
+material is incorrectly licensed remains with the distributor, as
+always.
+
+We hope this additional licensing will make our fonts even more widely
+available and usable in the free software community, such as the TeX
+Gyre Project.
+
+Sincerely,
+Peter Rosenfeld (Managing Director, URW++)
