A physics-to-JSON and JSON-to-physics utility that creates human-readable output useful for version control systems such as git. You can then edit these JSON files using a text editor, another program, etc. and turn them into physics files. Also included are utility scripts for:

• viewing differences between git commits for physics, between any two non-tracked files, or between some mixture of these
• retroactively building a parallel set of commits for a JSON version of one or more physics files' existing history
• automatically generating JSON for every committed physics file, bundling the JSON into the commit

Source code and binaries are available on my website; also available there are signatures for individual binaries. I recommend using them to verify whichever you might run.

For verification purposes, here is my public key fingerprint:

Rolling release based on the current production branch of code.
