Parchment is an app development toolkit for the Cardstock operating system. It handles app uploading and packaging automatically.

The project is currently in an unfinished state. It currently supports packaging apps in the custom .cpkg (Cardstock Package) format, and can automatically detect an attached Cardputer and put it in dev mode. The actual file transfer protocol is currently unimplemented, and Parchment does not currently handle initializing a Cardstock application in the way a development system like NPM can. These features are planned.
