0install

Package a new app, tool, or library for Zero Install (0install) in the apps.0install.net repository — authoring its feed (`.xml`), 0template template (`.xml.template`), and 0watch version-detection script (`.watch.py`), then generating and verifying the feed with 0template/0watch. Use this whenever the user wants to add or package a new program for 0install / apps.0install.net (e.g. "add ripgrep to 0install", "create a feed/template for <project>", "write a watch script for <tool>", "package <X> as a 0install feed").
