It is easy to extend TCL. You write a routine in C and then
compile it to a libXXX.so file using some naming convention.
TCL can then load the new command. Kind of like a
Perl Module. My idea was to NOT write a parser. I'd just add
commands to an existing language. You could do the same with
Perl. Just define a Perl function called "Exspose", "Nove_to" and
so on. You'd pickup all the rest of Perl for free/

It's the same as you said above. "5) scan the sky preferring these
fields if available"
