Subject RE: Mail a nice pretty html build log...
Date Wed, 15 Jun 2005 18:16:59 GMT
Here is the code. Line 82 - 87 is where the work is needed. Could parameterize some stuff also.
This is mostly the same as the MailLogger, in fact that was my starting point, as you may
notice the documentation section below the imports has not been updated.
