+compiled with the GNU C compiler, on various types of @sc{cpu}. So the
+kinds of portability that are absolutely necessary are quite limited.
+But it is important to support Linux-based GNU systems, since they
+are the form of GNU that is popular.
+
+Beyond that, it is good to support the other free operating systems
+(*BSD), and it is nice to support other Unix-like systems if you want
+to. Supporting a variety of Unix-like systems is desirable, although
+not paramount. It is usually not too hard, so you may as well do it.
+But you don't have to consider it an obligation, if it does turn out to
+be hard.
@pindex autoconf
The easiest way to achieve portability to most Unix-like systems is to
collection. For a single short document, you can use a very permissive
non-copyleft license, to avoid taking up space with a long license.
+See @uref{http://www.gnu.org/copyleft/fdl-howto.html} for more explanation
+of how to employ the GFDL.
+
+Note that it is not obligatory to include a copy of the GNU GPL or GNU
+LGPL in a manual whose license is neither the GPL nor the LGPL. It can
+be a good idea to include the program's license in a large manual; in a
+short manual, whose size would be increased considerably by including
+the program's license, it is probably better not to include it.
