[Q] How to specify options for 'setup.py install' by environmentvariable?

[Makoto Kuwata]

Hi,

"setup.py install" command supports options such as --prefix,
--install-scripts, and so on.
For example:

$ python setup.py install --prefix=$PWD/local --install-scripts=$PWD/bin

Question: is it possible to specify these options by environment variable?
I want to specify --prefix or --install-scripts options, but it is
too troublesome for me to specify them in command line every time.
