The line MakeRobustmylib makes mylib robust, so that you can use it in the argument of commands like section or caption. The line pdfstringdefDisableCommands (used only if hyperref is loaded) makes mylib produce a sensible PDF outline entry when used in section. If you then do section{Library mylib{lipsum}} it won't break (because of MakeRobust), and the PDF outline will say Library 'lipsum'.
