+# `rustc-workspace-hack`
+
+This crate is a bit of a hack to make workspaces in rustc work a bit better.
+The rationale for this existence is a bit subtle, but the general idea is that
+we want commands like `./x.py build src/tools/{rls,clippy,cargo}` to share as
+many dependencies as possible.
+
+Each invocation is a different invocation of Cargo, however. Each time Cargo
+runs a build it will re-resolve the dependency graph, notably selecting
+different features sometimes for each build.
+
+For example, let's say there's a very deep dependency like `num-traits` in each
+of these builds. For Cargo the `num-traits`'s `default` feature is turned off.
+In RLS, however, the `default` feature is turned. This means that building Cargo
+and then the RLS will actually build Cargo twice (as a transitive dependency
+changed). This is bad!
+
+The goal of this crate is to solve this problem and ensure that the resolved
+dependency graph for all of these tools is the same in the various subsets of
+each tool, notably enabling the same features of transitive dependencies.
+
+All tools vendored here depend on the `rustc-workspace-hack` crate on crates.io.
+When on crates.io this crate is an empty crate that is just a noop. We override
+it, however, in this workspace to this crate here, which means we can control
+crates in the dependency graph for each of these tools.
