+nxtagspkgsfetch.sh
+------------------
+
+This script downloads all NuttX RTOS and Application snapshot packages
+from the upstream git repository based on the provided git tags list.
+These are NOT official release packages as checksum will differ.
+When launched from the local NuttX git repository clone the script will
+obtain all available tags to be downloaded, otherwise list of tags needs
+to be provided manually (or when just selected tag is required).
+This script uses ``wget`` underneath, make sure this tool is installed.
+Fetch log file is created with a timestamp in name next to the packages.
+
+Having all tags packaged is important for changes comparison
+between specific versions, testing a specific version, compatibility
+checks, searching for a feature introduction timeline, etc.
+
+Usage: ``./nxtagspkgsfetch.sh [download_path] [tags_list_space_separated]``
+
+You can provide optional download path (default ``../../nuttx-packages``)
+and tags list to get packages for (default all tags from local git clone).
+When providing tags you also need to provide download path.
