## Bash script to setup PX4 development environment on Ubuntu LTS (18.04, 16.04).
## Can also be used in docker.

## Installs:
## - Common dependencies and tools for nuttx, jMAVSim, Gazebo
## - NuttX toolchain (omit with arg: --no-nuttx)
## - jMAVSim and Gazebo9 simulator (omit with arg: --no-sim-tools)
##
## Not Installs:
## - FastRTPS and FastCDR
