+Robert Deters:
+
+  I have attached some revisions for the UIUCModel and some LaRCsim.
+  The only thing you should need to check is LaRCsim.cxx.  The file
+  I attached is a revised version of 1.5 and the latest is 1.7.  Also,
+  uiuc_getwind.c and uiuc_getwind.h are no longer in the LaRCsim
+  directory.  They have been moved over to UIUCModel.
