OK, now it uses sys.[exec_]prefix and supports
a -o option to specify an output directory. *Much* more convenient. Removed a whole lot of hullabaloo from the README file, too.

More than one -e option may be given.

In order to use freeze successfully, you must have built Python and

installed it ("make install").

The -p and -P options passed into the freeze script must correspond to

the --prefix and --exec-prefix options passed into Python's configure

script.

The script should not use modules provided only as shared libraries;
