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