Documentation:
Function to translate links with different syntax to Org syntax.
This can be used to translate links created for example by the Planner
or emacs-wiki packages to Org syntax.
The function must accept two parameters, a TYPE containing the link
protocol name like "rmail" or "gnus" as a string, and the linked path,
which is everything after the link protocol. It should return a cons
with possibly modified values of type and path.
Org contains a function for this, so if you set this variable to
`org-translate-link-from-planner', you should be able follow many
links created by planner.

You can customize this variable.
