Support using -p/-P to point to the source/build directory instead of

Browse source 
the install directory.  Added -h option to print the full usage
message; by default, only two lines are now printed for errors.

Options:
-p prefix: This is the prefix used when you ran ``name install''
-p prefix: This is the prefix used when you ran ``make install''
in the Python build directory.
(If you never ran this, freeze won't work.)
The default is whatever sys.prefix evaluates to.
It can also be the top directory of the Python source
tree; then -P must point to the build tree.
-P exec_prefix: Like -p but this is the 'exec_prefix', used to
install objects etc. The default is whatever sys.exec_prefix
evaluates to, or the -p argument if given.
If -p points to the Python source tree, -P must point
to the build tree, if different.
