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.]]
