 Gender:
 For Some languages the numbers differ for gender and plural
 Use the option argument 'f' for female, 'm' for male and 'n' for neuter in languages like Portuguese, French, Spanish and German.
 use the option argument 'c' is for commune and 'n' for neuter gender in nordic languages like Danish, Swedish and Norwegian.
 use the option argument 'p' for plural enumerations like in German
 
 Date/Time functions currently have less languages supported than saynumber().

 Note that in future, we need to move to a model where we can differentiate further - e.g. between en_US & en_UK

 See contrib/i18n.testsuite.conf for some examples of the different syntaxes

 Portuguese sound files needed for Time/Date functions:
 pt-ah
 pt-ao
 pt-de
 pt-e
 pt-ora
 pt-meianoite
 pt-meiodia
 pt-sss

 Spanish sound files needed for Time/Date functions:
