+                               ========
+                               <shells>
+                               ========
+
+This is a collection of Nix expressions for use with nix-shell.
+
+The idea is that if I'm working on a bunch of Rust programs, I don't
+want to have to copy or write a shell.nix with all the standard Rust
+stuff for every program -- rustc, cargo, rust-analyzer, etc.
+
+So instead of doing that, I have a "shells" directory in my NIX_PATH,
+containing a "rust.nix" file.  When I just want to build some program
+as a one off, I'll just do this:
+
+    nix-shell rust.nix
+
+And if it's something I'm going to be working on long term, and I want
+to use lorri and stuff, I can create a shell.nix that just contains
+
+    import <shells/rust.nix>
+
+I could even extend it with project-specific dependencies like
+pkg-config or OpenSSL.
+
+Either way, I can now just modify rust.nix to add things to all my
+Rust environments at once, and store these environments with all my
+other Nix configuration.  Yay!
