jiri is a command-line tool for managing multi-repository projects. jiri was originally designed to aid Vanadium development, but has since been extracted into a standalone project, and is now used by various other projects.

jiri is available here: https://github.com/vanadium/go.jiri

The "fetch repositories" step of Vanadium installation installs the jiri tool in $JIRI_ROOT/.jiri_root/scripts.

Run jiri help to learn more about the tool. (Note, this command assumes your PATH contains $JIRI_ROOT/.jiri_root/scripts.)
