• Complete rewrite of BackRest::File module to use a custom protocol for remote operations and Perl native GZIP and SHA operations. Compression is performed in threads rather than forked processes.
• Fairly comprehensive unit tests for all the basic operations. More work to be done here for sure, but then there is always more work to be done on unit tests.
• Removed dependency on Storable and replaced with a custom ini file implementation.
• Added much needed documentation (see INSTALL.md).
• Numerous other changes that can only be identified with a diff.
