32  I (jjf) am strongly in favo(u)r of language support for an open
33  source project, but I have tried to make it as lightweight as
34  possible in the sense that only a subset of messages need to be
35  defined - the rest default to US English. There will be different
36  sets of messages for each component - so at present there is a
37  Clp component and a Coin component.
39  Because messages are only used in a controlled environment and have no
40  impact on code and are tested by other tests I have included tests such
41  as language and derivation in other unit tests.
