I've just released version 0.2.1 of distlib on PyPI [1]. For newcomers, distlib is a library of packaging functionality which is intended to be usable as the basis for third-party packaging tools. The main changes in this release are as follows:     Fixed issue #58: Return a Distribution instance or None from locate().     Fixed issue #59: Skipped special keys when looking for versions.     Improved behaviour of PyPIJSONLocator to be analogous to that of other     locators.     Added resource iterator functionality.     Fixed issue #71: Updated launchers to decode shebangs using UTF-8.     This allows non-ASCII pathnames to be correctly handled.     Ensured that the executable written to shebangs is normcased.     Changed ScriptMaker to work better under Jython.     Changed the mode setting method to work better under Jython.     Changed get_executable() to return a normcased value.     Handled multiple-architecture wheel filenames correctly. A more detailed change log is available at [2]. Please try it out, and if you find any problems or have any suggestions for improvements, please give some feedback using the issue tracker!
