# Expects two env variables:
# PYCHARM_ENGULF_SCRIPT = which script should be engulfed.
# PYCHARM_PREPEND_SYSPATH = which entries should be added to the beginning of sys.path;
#     items must be separated by path separator. May be unset.
#
# Given script is loaded and compiled, then sys.path is prepended as requested.
# On win32, getpass is changed to insecure but working version.
# Then the compiled script evaluated, as if it were run by python interpreter itself.
# Works OK with debugger.
