For the latter two we should invent something to help people. I know it
should be a general Python solution, but as none seems to be
forthcoming (lots of people have been asking about a way to access data
files, and the party line still seem to be "put them in your package",
even though that breaks with py2exe and zip imports and such) we should
roll our own, I think.
We already have a working example in macresource, which solves a
similar problem (finding a resource file, if the resources don't happen
to be in the resource fork of the current executable already).
For opening data files the API would have to be something different,
probably along the lines of filename =
datafile.datafilename("mydatafile.txt", "mymodule"), where
mydatafile.txt is first looked up in a directory specifically for
datafiles (where it would be found if the program was run as a .app
bundle), then in the same directory as mymodule.__file__.
For OSX bundles the datafile-directory specified above would be
Contents/Resources, and people on other platforms using py2exe or
somesuch are free to tag on to the scheme and invent their own magic
location:-)
