+# Generate the $CARGO_HOME/config necessary to use our local registry and settings.
+# Cargo can also be configured through environment variables in addition to the TOML syntax below.
+# For each configuration key below of the form foo.bar the environment variable CARGO_FOO_BAR
+# can also be used to define the value.
+# Environment variables will take precedent over TOML configuration,
+# and currently only integer, boolean, and string keys are supported.
+# For example the build.jobs key can also be defined by CARGO_BUILD_JOBS.
+# Or setting CARGO_TERM_VERBOSE=false in make.conf will make build quieter.
