1999-06-24 bertrand <Bertrand.Guiheneuf@inria.fr> * camel/camel-simple-data-wrapper.[ch]: new class. Simple implementation of a data wrapper: simply keeps the stream result in a byte array. * camel/camel-mime-part.c (_parse_header_pair): added a warning. Have to think about the correct way to store content type stuff. svn path=/trunk/; revision=995
