Good to know, thanks.
But how can I create such a egg?
And if this is possible, what do you think is the reasons why packages
like pyqt do not release such eggs?

Ah, right; I was thinking to created shortcuts.
It should not be hard to track installed dependencies, as an example
using the --record option of easy_install, and then registering all
installed files (and directories) with `file_created` and
The only problem is that created directories are not reported in the
record, but if files are always listed ordered, it should not be a problem.
Some other related questions:
* Do you think you can change ez_setup.py so that the code used to
check if setuptools must be installed is available as a separate
I need to check if setuptools must be installed so that I can pop a
For normal package dependencies (and assuming setuptools is
available) I can just use working_set.__contains__(dist)
* Is it safe to call `ez_setup.use_setuptools` setting `to_dir`
parameter to `sysconfig.get_python_lib()`?
By default the setuptools egg is copied to the same directory where
the bdist_wininst file is, and this is not safe since the user may
delete these files.
* Is it possible to get the ID of the main window of the bdist_wininst
I need it because MessageBox function requires the ID of the parent
It is possible to use the Desktop as parent, but this may cause
problems (message box displayed in the wrong position, with incorrect
focus, or who know)
* Is it possible to modify bdist_wininst (in a future release) so that,
when executing the post install script, the name of the project being
installed is passed in argv?
This change does not break existing code.
