Class
    Foam::functionEntries::includeFuncEntry
 
Description
    Specify a functionObject dictionary file to include, expects the
    functionObject name to follow with option arguments (without quotes).
 
    Searches for functionObject dictionary file in user/group/shipped
    directories allowing for version-specific and version-independent files
    using the following hierarchy:
    - \b user settings:
      - ~/.OpenFOAM/<VERSION>/caseDicts/functions
      - ~/.OpenFOAM/caseDicts/functions
    - \b group (site) settings (when $WM_PROJECT_SITE is set):
      - $WM_PROJECT_SITE/<VERSION>/etc/caseDicts/functions
      - $WM_PROJECT_SITE/etc/caseDicts/functions
    - \b group (site) settings (when $WM_PROJECT_SITE is not set):
      - $WM_PROJECT_INST_DIR/site/<VERSION>/etc/caseDicts/functions
      - $WM_PROJECT_INST_DIR/site/etc/caseDicts/functions
    - \b other (shipped) settings:
      - $WM_PROJECT_DIR/etc/caseDicts/functions
 
    The optional field arguments included in the name are inserted in 'field' or
    'fields' entries in the functionObject dictionary and included in the name
    of the functionObject entry to avoid conflict.
 
    Examples:
    \verbatim
        #includeFunc Q
        #includeFunc components(U)
        #includeFunc mag(Ux)
        #includeFunc mag(p)
    \endverbatim
 
    Other dictionary entries may also be specified using named arguments.
