# OVERVIEW
#
#   αcτµαlly pδrταblε εxεcµταblε
#
# DESCRIPTION
#
#   This file defines the libraries, runtimes, and build rules needed to
#   create executables from your Linux workstation that'll run anywhere.
#   Loading this package will make certain systemic modifications to the
#   build like turning off the System V "Red Zone" optimization, because
#   αcτµαlly pδrταblε εxεcµταblεs need to be able to run in kernelspace.
