| # important place to fiddle with for anyone interested in |
| # installation schemes for the Python library. Issues that |

| # * how much platform dependence should be here, and |

| # older, and then do it "the right way" for 1.6? Or should |
| # we install a site.py along with Distutils under pre-1.6 |
| # Python to take care of the current deficiencies in |
| # Python's library installation scheme? |
| # |
| # Currently, this method has hacks to distinguish POSIX from |
| # non-POSIX systems (for installation of site-local modules), |

| # by sysconfig). If the user supplied a prefix (and possibly |
| # exec_prefix), then we generate our own installation directories, |
