Minify ships with "Builder", a simple Javascript app for constructing URIs to use with Minify. ([screenshots of the 2.1.0 version](http://www.mrclay.org/index.php/2008/09/19/minify-21-on-mrclayorg/))
It also does some run-time checks of your PHP and Minify configuration to look for problematic settings like [auto-encoding](CommonProblems.wiki.md#output-is-distortedrandom-chars).
