[O] Annotating org exporters

[Sebastian Fischmeister]

Hi,

Is there a simple way to build regex-based extensions to the exporters?
For example, I would like to convert this string "=>" to $\rightarrow$
when converting the document to latex.

There are lots of other uses, where I could create my shortcuts and
insert them in orgmode files without creating a lot of clutter in the
file.
