FOLLOW and EXPORT are two functions.

FOLLOW should take the link path as the single argument and do whatever

a mail message.
|
|
EXPORT should format the link path for export to one of the export formats.
|
It should be a function accepting three arguments:
|
|
path the path of the link, the text after the prefix (like \"http:\")
|
desc the description of the link, if any
|
format the export format, a symbol like `html' or `latex' or `ascii'.
|
|
The function may use the FORMAT information to return different values
|
depending on the format. The return value will be put literally into
|
the exported file. If the return value is nil, this means Org should
|
do what it normally does with links which do not have EXPORT defined.
|
|
Org mode has a built-in default for exporting links. If you are happy with
|
this default, there is no need to define an export function for the link
|
type. For a simple example of an export function, see `org-bbdb.el'.

If TYPE already exists, update it with the arguments.
