This file contains all the local user configuration for your build environment. If there is no local.conf present, it is created from local.conf.sample. The local.conf file contains documentation on the various configuration options. Any variable set here overrides any variable set elsewhere within the environment unless that variable is hard-coded within a file (e.g. by using '=' instead of '?='). Some variables are hard-coded for various reasons but these variables are relatively rare.

Edit this file to set the MACHINE for which you want to build, which package types you wish to use (PACKAGE_CLASSES), where you want to downloaded files (DL_DIR), and how you want your host machine to use resources (BB_NUMBER_THREADS and PARALLEL_MAKE).
