Here is a testmodule. Here we show how to compile it within the
pfe source tree. With reading through autoconf/automake a bit
it should be easy to gather the information how to compile it
even outside the pfe sourcetree. When you want to add another
"testmodule" for your ideas, please do the following:

- create a toplevel subdirectory in parallel to "testmodule"
- copy the files from "testmodule" into that new subdirectory
- modify toplevel configure.ac, somewhere near the end you
  need another ARG_WITH followed by the if...fi clause that
  implants your subdirectory into the build process.
- modify toplevel Makefile.am only in the case that you want
  to store the complete sourcetree somewhere - add your new
  subdirectory to DIST_SUBDIRS and ACSUBDIRS
- change into your new subdirectory and start modifying the
  testmodule example. Be sure to replace anything that is
  called "testmodule" of course.

That's about it, the files in this subdirectory are given
away under the ZLIB License. Basically, it requires that
you change everything and that you take all liabilities.
See the file COPYING.ZLIB for details.
