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.
38
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.
42 */

44 Where there are derived classes I (jjf) have started message numbers at 1001.
