Frame.js

Frame.js is a flow control library and script loader for Javascript applications. Frame includes and acts as an interface for the LABjs library loader. So you can use Frame to load script libraries from both local and remote servers, cross-browser, with no cross-site scripting restrictions. While many function sequencers exist, Frame.js focuses on application-level synchronous function management, includes a library loader to mix-and-match between remote scripts, local scripts, and functions, and provides a basic set of debugging and unit testing tools. Frame is like require.js, but designed for the frontend, with debugging tools, and it clocks in at just under 11k (compared to require.js's minified 25k).
