+Note to hackers
+---------------
+
+When hacking on camel (and on the gnome mailer in general), 
+be sure to follow the same coding style as the intial authors.
+Please read the file HACKING in gnumeric and follow the
+general guidelines explained in it.
+
+Please take a look at camel source files and try to 
+imitate the coding style the best possible. We are perfectly
+aware that this is not the best and unique style, but it 
+is absolutely mandatory that Camel is homogeneous. 
+If you find the current coding style to have some weaknesses, 
+please contact the authors to discuss this matter.
+
+Thanks.
+
+	Bertrand.

+Important note for Camel hackers:
+---------------------------------
+
+Camel has been a lot of work, and has been conceived to be general
+enough to be used outside the gnome-mailer. It is possible in the
+future that it is used in softwares with licenses incompatible with the
+LGPL. For this reason, the copyright has to be owned by a unique
+person.  Be sure, however, that Camel will always be available under
+the LGPL.  Significant authors will always be consulted before any
+special use of Camel. Moreover, in special situations, they may be
+given the authorization to use Camel with a license different than the
+LGPL.
+
+Thus, when adding code in Camel, always add the following lines at the
+begining of the file:
+

+You may also want to add your name to the author name list after this
+header.

+Happy hacking,
