>From a's point of view, there is no c. But this works fine. Observe:
https://gist.github.com/4259909
Each module can load whatever is in its node_modules folder (or
parents), no matter where the module lives. Then that module, in its
actual realpath home, can load whatever is in its node_modules folder
(or parents), no matter where they actually live.
This is required because of the way that executables are typically
linked. On Unix, you have something like:
/usr/local/node_modules/foo/bin/foo.js
which does `require("../lib/foo-internals.js")`.
That script is linked to
/usr/local/bin/foo
If we didn't realpath, then it'd be looking for
/usr/local/lib/foo-internals.js instead of
/usr/local/node_modules/foo/lib/foo-internals.js.
Does that make sense?
