to override built-in defaults.

Values are NAME="VALUE" pairs, with # representing commented lines. most
commandline options have an equivalent. an example Debian based system with an
alternate base location, architecture, and distribution:

 # set alternate default location for ltsp chroot (\-\-base)
 BASE="/srv/ltsp"
 # build an amd64 chroot by default (\-\-arch)
 ARCH="amd64"
 # build a Debian sid environment (\-\-dist)
 DIST="sid"
