STR-172, martin:
Maybe this mechanism should not be designed to be used by hand: there is a strong case for using a more declarative description of command-line arguments (DocBook, Niels’ work on XTC) and deriving the actual implementation from this. Now the XML tools are in StrategoXT, this shouldn’t be a big problem.

STR-172, martin:
Requires more thinking about a tool specification. Also, we must fix compiler issues first.
