"""Post-generation fix for XcodeGen issue #1549: XcodeGen does not link
XCSwiftPackageProductDependency entries to local (path-based) Swift packages,
which makes the Xcode GUI report "Missing package product". This script
attaches the MartinOMEMO product dependencies to the vendored local package
reference in the generated project file.

Run after every `xcodegen generate` (see the Makefile `project` target).
