1// Function to determine whether a path is in the package.bin set.
2// Used to prevent issues when people publish a package from a
3// windows machine, and then install with --no-bin-links.
4//
5// Note: this is not possible in remote or file fetchers, since
6// we don't have the manifest until AFTER we've unpacked.  But the
7// main use case is registry fetching with git a distant second,
8// so that's an acceptable edge case to not handle.
