Eggdoc examples are in src/.

These particular examples are the source code to several of my extensions, and
require eggdoc-zb.scm for licensing and homepage information.  This file is
also under src/ and must be in your (use) path, which includes the current
working directory.  So, for example, you can regenerate the documentation for
the args extension thusly:

cd src; csi -script eggdoc-args.scm > ../html/args.html
