/**
* Creates a debug and minified build, executing the `callback` for each.
* The `callback` is invoked with 2 arguments; (filepath, source)
* Compiles template files matched by the given file path `pattern` into a
* single source, extending `_.templates` with precompiled templates named after
* each template file's basename.
*
* @param {Array} options The options array.
* @param {Function} callback The function called per build.
* @private
* @param {String} pattern The file path pattern.
* @param {Object} options The options object.
* @returns {String} Returns the compiled source.
