If you write FooCad, don't regard LTrax as a program, but rather a family of
standard meta-commands. But as the "owner" of that family, I may change the
spec's and thus make FooCAD incompatible...
When it comes to LTrax - I know you most likely mentioned LTrax just as an
example - when it comes to LTrax, the syntax is still under development.
When it comes to more generic meta-commands, such as ROTATE, TRANSLATE, and
so on, I think it is so cross-tool that it's better to not have a specific
tool prefix. Hmm, I'm getting tired, wonder if anyone understands what I'm
trying to say...
What I think I try to say is that some meta-statements, like "Author:" is
very official and very staticly specified, other are less official and may
still under development.

Uhmm, not in the LTrax case - unless you plan to enhance the syntax.
