I'm a bit lost here. Are you talking about using ldglite to render
image files, or render interactively? I ask because -mf and -mF
ignore all STEP commands, but only for the non-interactive image file
generating usage. There is a -D command (that was added to a later
version of ldlite) to set the subfile level at which to ignore STEP
commands. See Version 2.3 Release Notes here.
http://ldlite.sourceforge.net/
I suppose it could make sense to use the -D command to also control
the subfile level at which to ignore CLEAR, and perhaps other
instruction formatting macros like ROTSTEP and such. I'm a bit fuzzy
on how well I incorporated the -D code from ldlite into ldglite,
especially with the L3 parser. I suppose I should test it with both
parsers and see how well it extends to the other meta commands. I
don't think there's much actual code involved.

Why is everyone so afraid of the source code?

Uh, yeah, I'm looking but I'm still having trouble figuring out how
it all fits together.
Don
Err, I set FUT to lugnet.cad.dev because I don't think my comments
really all that MLCad specific.
