-    These enviromental settings are useful to help develop with an
-    entirely local copy of the osg.  However, once you've done a
-    make install you can make do without all of these, although
-    OSGFILEPATH is still useful as the osgDB library uses it for
-    picking locating datafiles.

-    Add the following to your .cshrc :
-
-        setenv OSGHOME <location of OSG root>

-        setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${OSGHOME}/lib
-        setenv PATH ${PATH}:${OSGHOME}/bin

-    Or the following if you're using a sh compatible shell :
-
-        export OSGHOME=<location of OSG root>

-        export PATH=${PATH}:${OSGHOME}/bin

-    note: under IRIX you'll need to use LD_LIBRARYN32_PATH instead
-    of LD_LIBRARY_PATH.
