The templates include a stategy to simplify meshing with snappyHexMesh,
particularly to help generate an initial mesh quickly that can subsequently be
improved.  The templates are setup to enable rapid initial simulations, typically
with simpleFoam.  The initial templates cover simple inflow-outflow and closed
domains, including rotating geometry, and an example axisymmetric flow.  For
more details, consult the README file accompanying each template case.
The cases are located in $FOAM_ETC/templates

Description
    Specify an etc file to include when reading dictionaries, expects a
    single string to follow.

    Searches for files from user/group/shipped directories.
    The search scheme allows for version-specific and
    version-independent files using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/\<VERSION\>
      - ~/.OpenFOAM/
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/\<VERSION\>
      - $WM_PROJECT_SITE
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/\<VERSION\>
      - $WM_PROJECT_INST_DIR/site/
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/

    An example of the \c \#includeEtc directive:
    \verbatim
        #includeEtc "etcFile"
    \endverbatim

    The usual expansion of environment variables and other constructs is
    retained.
