+This directory is treated specially by the loaders.
+
+In particular, when running in chrome, a resource like
+"devtools/shared/platform/mumble" will be found in the chrome
+subdirectory; and when running in content, it will be found in the
+content subdirectory.
+
+Outside of tests, it's not ok to require a specific version of a file;
+and there is an eslint test to check for that.  That is,
+require("devtools/shared/platform/client/mumble") is an error.
+
+When adding a new file, you must add two copies, one to chrome and one
+to content.  Otherwise, one case or the other will fail to work.
