Mar 31, 2009

Internationalization in "import-file" command: support for character
encodings, more flexible tokenization patterns, and user-supplied

classifiers, use the option "--trainer MaxEnt,l1Weight=1.0".

memory, two new formats for saving topic-word weights to files, topic
inference for unseen documents.

Removed obsolete ant, lucene and junit jars, updated to JUnit 4.

Many bug fixes.
