[GNC-dev] import map editor

[Stefan Müller]

Hallo all,
as there isn't anyone in the user mailing list who can answer my 
question may someone here can help me out.

Can anyone explain the purpose of the "import map editor" shown in the 
tools menu?
All what I can find related to mapping imports is this:

<http://gnucash.1415818.n4.nabble.com/Fixing-confused-bayesian-matching-data-td4685819.html>
but there is nothing about the editor.

Can anyone explain how to use it is still empty after several csv imports.

Thank you

Stefan
