This is a simple filter program which converts a valid MSDL file into a
(hopefully) valid VRML file. The bulk of the code is contained within 
filter.c

THIS IS AN ALPHA RELEASE, and as such should be mistrusted! 
This release does not handle some MSDL object types (such as NURBS), 
and is known to have bugs in the rotation code for cylinders & discs.
