"""
Provides "invoke" script when invoke is not installed.
Note that this approach uses the "tasks/_vendor/invoke.zip" bundle package.
Usage::
# -- INSTEAD OF: invoke command
# Show invoke version
python -m tasks --version
# List all tasks
python -m tasks -l
.. seealso::
* http://pyinvoke.org
* https://github.com/pyinvoke/invoke
Examples for Invoke Scripts using the Bundle
-------------------------------------------------------------------------------
For UNIX like platforms:
.. code-block:: sh
#!/bin/sh
#!/bin/bash
# RUN INVOKE: From bundled ZIP file (with Bourne shell/bash script).
# FILE: invoke.sh (in directory that contains tasks/ directory)
HERE=$(dirname $0)
export INVOKE_TASKS_USE_VENDOR_BUNDLES="yes"
python ${HERE}/tasks/_vendor/invoke.zip $*
For Windows platform:
.. code-block:: bat
@echo off
REM RUN INVOKE: From bundled ZIP file (with Windows Batchfile).
REM FILE: invoke.cmd (in directory that contains tasks/ directory)
setlocal
set HERE=%~dp0
set INVOKE_TASKS_USE_VENDOR_BUNDLES="yes"
if not defined PYTHON set PYTHON=python
%PYTHON% %HERE%tasks/_vendor/invoke.zip "%*"

from __future__ import absolute_import
import os
import sys
# -----------------------------------------------------------------------------
# BOOTSTRAP PATH: Use provided vendor bundle if "invoke" is not installed
# -----------------------------------------------------------------------------
# NOTE: tasks/__init__.py performs sys.path setup.
