+## This module is based on Python's Unidecode module by Tomaz Solc, 
+## which in turn is based on the ``Text::Unidecode`` Perl module by 
+## Sean M. Burke 
+## (http://search.cpan.org/~sburke/Text-Unidecode-0.04/lib/Text/Unidecode.pm).
+##
+## It provides a single proc that does Unicode to ASCII transliterations:
+## It finds the sequence of ASCII characters that is the closest approximation
+## to the Unicode string.
+##
+## For example, the closest to string "Äußerst" in ASCII is "Ausserst". Some 
+## information is lost in this transformation, of course, since several Unicode 
+## strings can be transformed in the same ASCII representation. So this is a
+## strictly one-way transformation. However a human reader will probably 
+## still be able to guess what original string was meant from the context.
+##
+## This module needs the data file "unidecode.dat" to work, so it has to be
+## shipped with the application!
