+subdirectory.  Be sure to read the documentation in the Python

+

+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.
