I went several rounds with [olimex] on a board, trying to satisfy
    their solder mask requirements in Eagle.  It turns out that their
    script (and the requirements!) are a little wacky, but it is possible
    to supply .BRD files to them if that's what you want to do.

My interpretations of Olimex's requirements and Eagle's defaults (and
the values in most of the Eagle-provided libraries) is that they don't
match up very well :-( There are a bunch of tools for "adjusting" the
necessary things in Eagle (including one by me!), but most of them are
set up to operate within the "CAM" output process (that produces
gerber and drill files), rather than on the board itself.  So you can
adjust your drill sizes and make a silkscreen layer with adjusted line
widths, but the new values are all in the drill files and the new
layer, not in the "standard" layers.  So it looks to me like it would
be easier to NOT send the .BRD files?  Sure, Olimex might be able to
do all that for you, but it seems like a larger amount of "what you
saw was NOT what you got" than I'd feel comfortable with.  Disenting
opinions from people with more actual experience gladly welcomed.


    Anyway, if someone needs to run SILKWIDTH.ULP, contact me and I can
    send you my modified copy and give you some pointers for running it.

silkwidth.ulp had a lot of bugs.  My improved version is silk-new.ulp,
and it's got more features as well as bug fixes.  (Note that the new
features are largely aimed at being able to "etch" a silkscreen using
an LPKF PCB router on the copper, so perhaps they're not generally all
that useful...)
