The sample project that demonstrates how jQuery and RequireJS can be used together has been moved to its own repository. This should make it easier to update. As proof, it now has jQuery 1.5.2, and can be downloaded here.
Also, the sample project has gone back to using an integrated RequireJS+jQuery file as the basis for the example. Keeping RequireJS and jQuery separate and using the "priority" configuration option in jQuery has some edge case considerations that required more explanation than what most people need. However, the README in the sample project repository explains how to use the priority configuration if you prefer to use that option.
