Subject Re: [scxml-eclipse] Managing generated code in SVN
Date Fri, 11 Jun 2010 02:03:03 GMT
Hi Rahul,

Deleting files in SVN server last time is due to my lapse operation,
sorry for that :-(
In fact, pattern in (B) is not avaiable, we can not help developers
generate all the necessary code by theirselves because we can only
generate basic source code and we must change source code by hand to
achieve our aim. So, i think we can use pattern A and i will be MORE
and MORE careful to maintain SVN workspace.
