# Notes:
#
# As we're using an "if" statement,
# we need to use ";" and "\" at the end of lines,
# else make would consider each line to be a separate command to call,
# which doesn't work.
# Using ";" and "\" at the end of lines helps make
# interpret this "if" as one single statement/command.
#
# You can replace ";" with "&&" if you need to stop the
# execution process before running next commands.
