Python3 ======= Source ------ Python3 portage is made by running the 2to3 script on all modules:: find . ! -path "*/test/*py" -name "*py" -exec 2to3-3.1 -wn {} \; Dev --- If you want to run the tests, simply remove the "! -path ..." option, hence also refactoring the test files, including all data files. Note that when running 2to3 on some test/input/ files, it will crash since this folder contains corrupted files. Hence, we can not run directly *2to3* on the test folder:: $ 2to3 test/ But it will work nice with *find*. Debian ------ For the Debian packaging, you can use the debian.py3k/ content against the debian/ folder:: cp debian.py3k/* debian/
