+directory, which creates an executable named osse.

+Before running osse, the initial ensemble needs to be set up by
+running the mkens script in verification/osse/da.  mkens creates the
+directories, symbolically links files necessary to run the model, and
+copies in the initial ensemble files.  osse should be run from the
+directory verification/osse/da/inits since it expects the ensemble
+members to be one directory above.  It also expects to have in its
+working directory the file iobsloc-003.txt, which contains the
+locations of the observations.  This file is located in
+verification/osse/da/inits.
