    00032 /*
    00033  I (jjf) am strongly in favo(u)r of language support for an open
    00034  source project, but I have tried to make it as lightweight as
    00035  possible in the sense that only a subset of messages need to be
    00036  defined - the rest default to US English.  There will be different
    00037  sets of messages for each component - so at present there is a
    00038  Clp component and a Coin component.
    00039
    00040  Because messages are only used in a controlled environment and have no
    00041  impact on code and are tested by other tests I have include tests such
    00042  as language and derivation in other unit tests.
