Some of the pieces are falling into place, but I'm still chewing on something.
Let me rephrase my goal with added details: As a library author, I need my users to have ONE command that safely installs a package with collection paths that would collide in a user or (system) installation scope. The docs on package scopes and your email make it sound like I have to ask my users to create and configure an installation, and make sure no colliding packages exist at user scope. All before installing the package. Can your recipe be done in one step? If not, I think that's where I'd like to contribute. ~slg ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Thursday, April 30, 2020 3:24 PM, Matthew Flatt <mfl...@cs.utah.edu> wrote: > Consider viewing "project" scope as "installation" scope, where an > existing installation becomes a wider scope after "installation".
