#! /usr/bin/env bash

## Bash script to setup PX4 development environment on Arch Linux.
## Tested on Manjaro 18.0.1.
##
## Installs:
## - Common dependencies and tools for nuttx, jMAVSim
## - NuttX toolchain (omit with arg: --no-nuttx)
## - jMAVSim simulator (omit with arg: --no-sim-tools)
## - Gazebo simulator (not by default, use --gazebo)
##
## Not Installs:
## - FastRTPS and FastCDR
