// Each key in the *sources* variable must be an array of
// the source files that will be combined into a single
// file and stored in *outputDir*. Each key in *sources*
// must be also present in *output*, whose value indicates
// the filename for the output file which combines the
// contents of the source files.
//
// Keys must be camel cased and end with either 'Css' or
// 'Js' (e.g. someSourcesCss or someSourcesJs). For each
// key, a build task will be generated named by prepending
// 'build-' and converting the key to dash-separated words
// (e.g. someSourcesCss will generate build-some-sources-css).
//
// Tasks with names ending with '-js' will be executed by the
// build-all-js task, while the ones ending with '-css' will
// be done by build-all-css. There's also a build task which
// runs both build-all-css and build-all-js.
//
// The watch task will monitor any files mentioned in the *sources*
// variable and regenerate the corresponding output file when
// they change.
//
// See README.md for details on the other tasks.
