The main task to keep it working is maintaining the command line parameters
to support the latest version of the MRSIDS utilities. I'll be doing that
for SkyJUMP so it is a simple matter to keep OJ up to date too. MRSID,
ECW, and ArcSDE are OpenJump's gateway to the non-free GIS world. Some of
us are still tied to the commercial and government sector.

Larry
