#
#  Builds custom upload command
#    1) Run platformio as a subprocess to find a COM port
#    2) Build the upload command
#    3) Exit and let upload tool do the work
#
#  This script runs between completion of the library/dependencies installation and compilation.
#
#  Will continue on if a COM port isn't found so that the compilation can be done.
