python-stemmer-dbg 1.3.0+dfsg-1build4 (armhf binary) in ubuntu xenial

 PyStemmer provides access to efficient algorithms for calculating a "stemmed"
 form of a word. This is a form with most of the common morphological endings
 removed; hopefully representing a common linguistic base form.
 .
 PyStemmer provides algorithms for several (mainly European) languages, by
 wrapping the libstemmer library from the Snowball project in a Python module.
 .
 This package contains the extensions built for the Python debug interpreter.
