This paper describes opportunities for automatically modernizing Erlang applications, cleaning them up, eliminating certain bad smells from their code and occasionally also improving their performance. In addition, we present concrete examples of code improvements and our experiences from using a software tool with these capabilities, tidier, on Erlang code bases of significant size. Categories and Subject Descriptors D.2.7 [Software Engineering]: Distribution, Maintenance, and Enhancement—Restructuring, reverse engineering, and reengineering General Terms Design, Languages Keywords program transformation, refactoring, code cleanup, code simplification, Erlang
