The modules in this package provide the functionalities which are used by Roundup - adapting the most recent Python usage - using new built-in functionality - avoiding deprecation warnings Use the modules in this package to preserve Roundup's compatibility. # vim: si code-e1e3531b4d9b/roundup/anypy/TODO.txt0000644000000000000000000000020012744471320016065 0ustar 00000000000000Python compatiblity TODO ~~~~~~~~~~~~~~~~~~~~~~~~ Remove support for Python versions < 2.5.
