# SYNOPSIS
#
#   Cosmopolitan Core Build Rules
#
# DESCRIPTION
#
#   This file shows GNU Make how to convert between file types, based on
#   their extensions. We use everyday, ordinary, boring, and ubiquitous
#   system commands for everything, e.g. as, cc, ld, etc. with plain and
#   simple shell-script wrappers, e.g. build/assemble and build/compile.
#   Those veneers abstract away most of the boring trivialities, to keep
#   our makefiles pristine and readable.
