The following commands are now possible. Note that the '$' sigil on the
FOAM_TUTORIALS environment variable has been escaped with '\' to prevent
it from being expanded to nothing in the outer/interactive shell.
~/OpenFOAM/OpenFOAM-dev/bin/foamExec ls \$FOAM_TUTORIALS/*
~/OpenFOAM/OpenFOAM-dev/bin/foamExec cp -r \$FOAM_TUTORIALS/incompressibleFluid/pitzDaily .
FOAM_INST_DIR is the location of the OpenFOAM installation which defaults to
the directory containing the etc/bashrc,cshrc file. If this default is
not appropriate FOAM_INST_DIR can be set explicitly.
