+
+This version of SERA is based on the Sera 1C1 release with changes to
+only include code that can be open sourced.
+
+WARNING:
+
+SERA was last tested over a decade ago with 32 bit machines and the
+compilers at the time. SERA also has had changes to remove previous
+versions of xmgr and libnurb from brlcad as the previous versions
+could not be distributed as open source. Use with current compilers
+has not been tested.
