+subdirectory.  Be sure to read the documentation in the Python
+distribution.
+
+Python requires library files such as string.py to be available in
+one or more library directories.  The search path of libraries is
+set up when Python starts.  To see the current Python library search
+path, start Python and enter "import sys" and "print sys.path".
+
+All PC ports except Windows 95/NT use this scheme to try to set up
+a search path:
+  1) If the Python executable (for example, py_dos.exe) is located
+     in a subdirectory of the Python root (..), then those library
+     files are used (../Lib) to generate the path.
+  2) Otherwise the environment variable PYTHONPATH is the search path.
+  3) Otherwise the directory "lib" in the directory of the executable
+     file is used to generate the path.
+  4) Otherwise, the current directory is used (not useful).
+
+The best installation strategy (except NT) is to put the Python
+executable in some convenient directory such as C:/python, and
+copy all library files and subdirectories (using XCOPY) to C:/python/lib.
+Then you don't need to set PYTHONPATH.  Otherwise, set the environment
+variable PYTHONPATH to your Python search path.  For example,
+   set PYTHONPATH=.;d:\python\lib;d:\python\lib\win;d:\python\lib\dos_8x3
+
+Python for Windows 95/NT uses the same PYTHONPATH environment variable, plus
+the Python path recorded in the registry.
