REM This script is located in the subfolder "shims"
REM in the plugin root directory.
REM
REM Call it by name in the special Windows CMD terminal,
REM which has been modified, calling "virtualenv.init".
REM
REM The script returns RC = 0 or another value in case of
REM error.
REM
REM NOTE: Command "setlocal" would jeopardize the deactivation.
REM    All local variables are global inside the shell.
REM    Finally, these must be cleaned to reduce risks.
