 That's right, we don't have automatic handling of zip files. You have to define
the extraction commands explicitly. See for example the python-keyring package.

 The reason we don't have automatic extraction of zip files is that it doesn't
have the --strip-components option of tar. For packages that put everything in a
<pkg>-<version> directory, you can just extract in $(BUILD_DIR). But of course,
a package that is crazy enough to use a zip file is unlikely to follow sane
conventions, so in many cases it will be in some other subdirectory. Or in the
case of python packages, the upstream package typically doesn't have the python-
prefix and we want that, so you have to move it to the right place. Like
python-keyring does.

 Please don't post HTML mails with all those annoying colours.
