Initial import of code Currently version 1.0.2 but with the 1.0.3 changes as given in the CHANGES file. Is about ready for a 1.0.3 release. [[This repository is actually a lift into git made in October 2011 of code history originally kept in CVS and later in Subversion. This import marks the point at which the original private CVS moved to public CVS on SourceForge. Due to technical problems with CVS and the CVS to Subversion conversion tools, portions of the early history have somewhat garbled metadata. Here and elsewhere in this repo, comments enclosed in curly braces were added at the time of the git lift in an attempt to document the problem.]]
