This required adding the included script in every project that links to
one of the bundled libraries. The script is designed to sleep for a
while if another thread is already extracting the libraries. The script
uses a temporary file as an extraction step lock, so other instances
sleep, and then detect the libraries.updated file, which is created
before the lock is removed.
