+/* This is the Porter stemming algorithm, coded up in ANSI C by the
+   author. It may be be regarded as cononical, in that it follows the
+   algorithm presented in
+
+   Porter, 1980, An algorithm for suffix stripping, Program, Vol. 14,
+   no. 3, pp 130-137,
+
+   only differing from it at the points maked --DEPARTURE-- below.
+
+   See also http://www.tartarus.org/~martin/PorterStemmer
+
+The algorithm as described in the paper could be exactly replicated
+by adjusting the points of DEPARTURE, but this is barely necessary,
+because (a) the points of DEPARTURE are definitely improvements, and
+(b) no encoding of the Porter stemmer I have seen is anything like
+as exact as this version, even with the points of DEPARTURE!
+
+You can compile it on Unix with 'gcc -O3 -o stem stem.c' after which
+'stem' takes a list of inputs and sends the stemmed equivalent to
+stdout.
+
+The algorithm as encoded here is particularly fast.

+Xerces library, structured queries allowing generalized field/tag paths,
+hierarchical result sets (XML only), automatic searching across multiple
+databases (allowing modular indexing), TREC format results, efficient
+indexing, and relatively low memory requirements during indexing (and the
+ability to index documents larger than available memory). Z39.50 support
+is available. Other features include Boolean queries, right truncation,
+phrase searching, relevance ranking, support for multiple documents per
+file, incremental indexing, and easy integration with other UNIX tools,
+The architecture is also designed to permit proximity queries; however,
+they are not fully implemented at present.
