Contributions by Ales Novak:

• RECompiler.compile() - copy on return
• RE.matchNodes() - BOL and EOL cases if RE.MATCH_MULTILINE is specified. - Think of RETest.java which prints MATCH!!!: ...... two times while in the older version only one time.
• RE.java also contains an extension which allow to parse InputStreams, Readers and char arrays in addition to Strings. All needed modifications are only in the RE class.

Contributions by Jon S. Stevens:

• Fix in the build system for building on NT
• Documentation fixes / additions
