This directory contains plugins used by the CLI to process Alloy projects:

• alloy.js -- This is the main Alloy plugin. This hooks into the CLI at the build.pre.compile stage to perform the alloy compile operation. The Alloy compile generates the set of files in the Resources directory which the CLI then compiles into the finished app.
• deepclean.js -- This hook extends the ti clean command for Alloy projects, emptying both the build and Resources directories.

For more information on CLI hooks, see the Titanium CLI Plugins guide.
