+Check with @code{gnu@@prep.ai.mit.edu}, for a possibly more current
+copy. You can also ftp it from a GNU FTP host in directory
+@file{/pub/gnu/tasks} - These files in different formats are available:
+@file{tasks.text}, @file{tasks.texi}, @file{tasks.info}, and
+@file{tasks.dvi}. It is also available on the GNU World Wide Web
+server: @file{http://www.gnu.ai.mit.edu}.

If you start working steadily on a project, please let @code{gnu@@prep}
know. We might have information that could help you; we'd also like to
send you the GNU coding standards.
-Because of the natural tendency for most volunteers to write
-programming tools or programming languages, we have a comparative
-shortage of applications useful for non-programmer users. Therefore,
-we ask you to consider writing such a program.

In general, a new program that does a completely new job advances the
GNU project more than an improvement to an existing program.

-A program to convert Postscript to plain ASCII text. Ghostscript will
-soon have a mode to output all the text strings in a document, each with
-its coordinates. You could write a program to start with this output
-and ``layout the page'' in ASCII. The program will be both easier and
-more useful if you don't worry pedantically about how the output text
-should be formatted. Instead, try to make it look reasonable as plain
-ASCII.
+A free program for public-key encryption.
+
+This program should use the Diffie-Helman algorithm for public key
+encryption, not the RSA algorithm, because the Diffie-Helman patent in
+the US will expire in 1997. It should use triple-DES, not IDEA, for
+block encryption because IDEA is patented in many countries and the
+patents will not expire soon. In other respects, it should be like PGP.
+
+This program needs to be written by someone who is not a US citizen,
+outside the US, to avoid problems with US export control law.
+
+Many people believe that PGP is free software, but that is not actually
+true. The distribution terms set by the copyright holders do not allow
+everyone to use and redistribute it.
