A set of template files from which to create an extension.
This extension can be built as-is, but will only result in the installation of a single, useless function.
You'll probably want to rename the extension to something more useful; use the supplied script thusly:
./rename.sh new_extension_name
This will convert occurrences of the original extension name in the relevant source files, then rename the files appropriately. No checks are performed on the validity of the name.
