In Choppascript, added the syntaxes [<], [>], and [pct] for escaping Choppascript special characters. Renamed the existing [> ...] syntax to [>> ...]. (This change was originally made in rocketnia-sites.)
Added lathe-fs.js, a library to do Node.js filesystem operations. These utilities originally appeared in rocketnia-sites's util.js, and now they're also used in Era.
