+Libtextcat is a library with functions that implement the
+classification technique described in Cavnar & Trenkle, "N-Gram-Based
+Text Categorization". It was primarily developed for language
+guessing, a task on which it is known to perform with near-perfect
+accuracy.
+     
+The central idea of the Cavnar & Trenkle technique is to calculate a
+"fingerprint" of a document with an unknown category, and compare this
+with the fingerprints of a number of documents of which the categories
+are known. The categories of the closest matches are output as the
+classification. A fingerprint is a list of the most frequent n-grams
+occurring in a document, ordered by frequency. Fingerprints are
+compared with a simple out-of-place metric. See the article for more
+details.
+     
+Considerable effort went into making this implementation fast and
+efficient. The language guesser processes over 100 documents/second on
+a simple PC, which makes it practical for many uses. It was developed
+for use in our webcrawler and search engine software, in which it it
+handles millions of documents a day.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
