Prepared from the 0.7.0 release source.
Source layout and packaging inputs follow Greyline86 Software Engineering Handbook 1.0.
The source archive is deterministic with a release-date mtime.
Python syntax and package payload paths were validated in the build environment.
Arch and Fedora packaging sources are included; binary packages require native target build environments.
