Uh Oh, we need some *unlicensed* documentation on this meta
command.  It's already used in some official parts.  If I have to
get permission in writing to use all the features of the official
parts (or be liable for unspecified damages) I'm gonna find myself
a new hobby.

Perhaps the use of the "ROTATION CENTER" meta statement in the parts
library can be changed into a different, non-licensed format?  The
word "CENTER" breaks the standing LDraw tradition of using British
English terms anyway.  In my opinion it should have been "CENTRE".

And it appears that the ROTATION meta statement is easily confused
with the LDLITE statement ROTATE, which may be a bad thing.

Meanwhile, Steve could you switch the parts tracker to use MLCAD
instead of ldglite to generate the image files?  The whole license
thing and especially the "liable for damages" part makes me nervous.
I don't want to be sued just because someone submits a part with
an MLCAD licensed extension and ldglite is used to convert it into
a picture.  I did a quick grep on ldraw.org of the files currently in
the tracker directory and found several files from several different
authors containing MLCAD ROTATION lines.  I didn't read much of
the MLCAD extension spec beyond the license so I have no idea what
other licensed extensions may be in there.

Thanks,

Don

(...) I do not think it is necessary, since the version of LDGLite we are using was developed before the MLCAD documentation was published. But maybe I should ban all non-Open Source software on Munin? (but that it would prevent the distribution of (...) (22 years ago, 30-Jul-02, to lugnet.cad.dev.org.ldraw)
