Class
    Foam::functionEntries::inputSyntaxEntry
 
Description
    Specify the dictionary scoping syntax, expects a single word to follow.
 
    An example of \c \#inputSyntax directive:
    \verbatim
        #inputSyntax dot
    \endverbatim
 
    The possible input syntax:
      - \par slash      use '/' as the scope operator
                            '../' to go to the parent dictionary
                            '!' to go to the top-level dictionary
 
      - \par dot        use '.' as the scope operator
                            '..' to go to the parent dictionary
                            ':' to go to the top-level dictionary
 
    The default dictionary syntax is \c slash but can be changed to \c dot in
    etc/controlDict
    \verbatim
        OptimisationSwitches
        {
            .
            .
            .
            inputSyntax dot;
        }
    \endverbatim
