I think a shell shortcut is a good workaround. It's less obtrusive
than a hard link since the script still has the same name. The command
line would be something like `"C:\Windows\pyw.exe"
"path\to\script.py"`. Clear the shortcut's "start in" field to make
pyw.exe inherit the working directory of the parent process. Add .LNK
to the PATHEXT environment variable to support executing "script.lnk"
as "script".
