+OSBF-Lua (Orthogonal Sparse Bigrams with confidence Factor) is a Lua C
+module for text classification. It is a port of the OSBF classifier
+implemented in the CRM114 project. This implementation attempts to put
+focus on the classification task itself by using Lua as the scripting
+language, a powerful yet light-weight and fast language, which makes it
+easier to build and test more elaborated filters and training methods.
