# Notes on building and running the regression tests
#
# The regress suite builds two sets of static executables: the former linked
# against the system libc, and the latter against the libc found in /usr/obj
# The idea is to compare the output of all programs with internal changes in
# the libc (more specifically the resolver).  They will be run in a chrooted
# environment to test various /etc configurations without touching the local
# machine config files.
#
# First, build a libc that needs testing, then:
#
# $ make
# $ doas make install
# $ doas make regress
#
# Tests output goes into a $REGRESSDIR/tmp.XXXXXXXXXX directory, and a digest
# is displayed at the end.
