# RPM builders, or people building in their home dirs:
# set PREFIX (default = /usr)
# set SYSCONFDIR (default = /etc)
# set INST_PREFIX (default = [same as PREFIX])
# set INST_SYSCONFDIR (default = [same as SYSCONFDIR])
#
# For example, to install in your home dir:
#
#   perl Makefile.PL PREFIX=/home/jm/sausr SYSCONFDIR=/home/jm/saetc
#
# Or to build a package in /tmp/build, but with its internal paths
# referring to /usr and /etc:
#
#   perl Makefile.PL PREFIX=/tmp/build/usr SYSCONFDIR=/tmp/build/etc \
#                       INST_PREFIX=/usr INST_SYSCONFDIR=/etc
#
# You can also override the automatic ./configure step by just
# running that yourself first.  But the plan is that this should not
# be necessary.
