Usage: #{ARGV[0]} SRCDIR APIDIR SPEC.xml [ ... ] TEMPLATE.rb [ ... ]
or: #{ARGV[0]} SRCDIR APIDIR SPEC.xml [ ... ] all [ makefragment.mk | makefragment.cmake ]
Parse all SPEC.xml files to create an AMQP model, run each TEMPLATE
putting the resulting files under SRCDIR, public API files in APIdir.
Prints a list of files generated to standard output.
If SRCDIR and APIDIR are '-' then just prints file list without generating files.
