    00032  I (jjf) am strongly in favo(u)r of language support for an open
    00033  source project, but I have tried to make it as lightweight as
    00034  possible in the sense that only a subset of messages need to be
    00035  defined - the rest default to US English.  There will be different
    00036  sets of messages for each component - so at present there is a
    00037  Clp component and a Coin component.
    00038
    00039  Because messages are only used in a controlled environment and have no
    00040  impact on code and are tested by other tests I have included tests such
    00041  as language and derivation in other unit tests.
    00042 */
    00043 /*
    00044   Where there are derived classes I (jjf) have started message numbers at 1001.
