A javascript development tool that merges several files into one
<p>Some time ago I saw a javascript library/development tool that takes several .js files (or modules, for that matter) and "compiles" it into one .js file. The goal of this tool is to facilitate the client-side development.</p>

<p>The sad thing is that I forgot the name of this tool. Does anyone knows the name of this library/tool (or some tool like this)?</p>
