+It takes one of the following values:
 
 * `y`, `yes`, `on`, `true` or no value: enable rpath.
 * `n`, `no`, `off` or `false`: disable rpath (the default).
 
+This flag only does something on Unix-like platforms (Mach-O and ELF), it is ignored on other platforms.
+
+If enabled, rustc will add output-relative (using `@load_path` on Mach-O and `$ORIGIN` on ELF respectively) rpaths to all `dylib` dependencies.
+
+For example, for the following directory structure, with `libdep.so` being a `dylib` crate compiled with `-Cprefer-dynamic`:
+
+```text
+dep
+ |- libdep.so

+
+This is primarily useful for local development, to ensure that all the `dylib` dependencies can be found appropriately.
