# This script helps installing tools required to use the ESP-IDF, and updating PATH
# to use the installed tools. It can also create a Python virtual environment,
# and install Python requirements into it.
# It does not install OS dependencies. It does install tools such as the Xtensa
# GCC toolchain and ESP32 ULP coprocessor toolchain.
#
# By default, downloaded tools will be installed under $HOME/.espressif directory
# (%USERPROFILE%/.espressif on Windows). This path can be modified by setting
# IDF_TOOLS_PATH variable prior to running this tool.
#
# Users do not need to interact with this script directly. In IDF root directory,
# install.sh (.bat) and export.sh (.bat) scripts are provided to invoke this script.
#
# Usage:
#
# * To install the tools, run `idf_tools.py install`.
#
# * To install the Python environment, run `idf_tools.py install-python-env`.
#
# * To start using the tools, run `eval "$(idf_tools.py export)"` — this will update
# the PATH to point to the installed tools and set up other environment variables
# needed by the tools.
