[Distutils] install_scripts and install_data commands

Do we have always Python scripts? What about shell scripts, and
specifically Windows Batch scripts?
See below for my current "Windows" hack in setup.py.

The "first python on the path" is the correct thing for the user,
otherwise the path is wrong. So "/usr/bin/env pyton" yields the correct
interpreter to execute.

PS. Here is my Distribution class form setup.py for LinkChecker:
# Autodetect the existence of an SSL library (this is pretty shitty)
# Autodetect Windows platforms to include the linkchecker.bat script
class LCDistribution(Distribution):
    default_include_dirs = ['/usr/include/openssl',
                            '/usr/local/include/openssl']

        self.check_ssl()
        self.check_windows()
        for cmd in self.commands:
            self.run_command (cmd)

    def check_ssl(self):
        incldir = self.has_ssl()
        if incldir:
            self.announce("SSL header file ssl.h found, "
                          "enabling SSL compilation.")
            self.ext_modules = [('ssl', {'sources': ['ssl.c'],

        else:

                          "disabling SSL compilation.\n"
