Future developments

Ideally a module could consist of:

A header file: lib/module.h
One or more implementation files: lib/module.c et al.
One or more autoconf macro files: m4/module.m4 et al.
A configure.ac fragment, Makefile.am fragment, dependency list: modules/module
A testsuite: source files in tests/ and metainformation (a configure.ac fragment, Makefile.am fragment, dependency list) in modules/module-tests
Some documentation
A POT file and some PO files
