Starting with Python 2.1, there is an easy solution. To discuss this, I assume you know what a codec search function is and how to register one (see codecs.register if you don't). Now, suppose you hava a package "japanese", containing a number of codecs. Inside japanese/__init__.py, register a search function for these codecs. So anybody importing "japanese" will get a codec "euc-jp". Install the "japanese" directory into site-packages. This works for all Python versions, but still requires applications to "import japanese". That is where a 2.1 feature comes into play: In site-packages, create a file "japanese.pth". In that file, add a single line import japanese Then, every time python starts, the japanese codecs will be automatically registered. HTH, Martin
