org-mode/org-rmail.el
Carsten Dominik 43eee81b3a Moved most of the linking code to separate files.
This files are stil all loaded automatically, but the user can turn
individual files off.  Also, this makes maintaining the link
stuff easier, because everything related to a specific link type
is in one place.
