Interesting. I originally used boilerpipe3 when testing NwalaTextUtils and had no issues.

I offered this solution because the author @anwala specified a dependency on the library at https://github.com/misja/python-boilerpipe/tarball/master#egg=python-boilerpipe.

According to Pypi, the boilerpipe3 library comes from https://github.com/slaveofcode/boilerpipe3. I was trying to offer the @anwala something closer to the original intention of the setup.py of NwalaTextUtils.

I do not get an error with the solution in this pull request. I do, however get a warning.

A glance at the resulting JSON indicates that it looks similar with either boilerpipe3 or misja/python-boilerpipe in spite of the warning.
