+# This script is used to re-package the esptool if needed and update the JSON file
+# for the Arduino ESP32 platform.
+#
+# The script has only been tested on macOS.
+#
+# For regular esptool releases, the generated packages already contain the correct permissions,
+# extensions and are uploaded to the GitHub release assets. In this case, the script will only
+# update the JSON file with the information from the GitHub release.
+#
+# The script can be used in two modes:
+# 1. Local build: The build artifacts must be already downloaded and extracted in the base_folder.
+#    This is useful for esptool versions that are not yet released and that are grabbed from the
+#    GitHub build artifacts.
+# 2. Release build: The script will get the release information from GitHub and update the JSON file.
+#    This is useful for esptool versions that are already released and that are uploaded to the
+#    GitHub release assets.
+#
+#    For local build, the artifacts must be already downloaded and extracted in the base_folder
+#    set with the -l option.
+#    For example, a base folder "esptool" should contain the following folders extracted directly
+#    from the GitHub build artifacts:
