# By default the following variables are defined:

# The exec_prefix and libdir variables contain unexpanded,literal ${prefix}.
# This is done on purpose. The idea is to be able to make this expansion
# late, so use can do:
# make install prefix=/my/own/prefix
#
# Now, we want to print those directories in the config.report, but we
# don't want to modify the actual variables. So we need to expand them.
# Since libdir contains $exec_prefix and exec_prefix contains $prefix, then
# to get the real value, we need to expand it twice.

  Now you can type "make" to build Kea. Note that if you intend to
  run "make check", you must run "make" first as some files need to be
  generated by "make" before "make check" can be run.

  When running "make install" do not use any form of parallel or job
  server options (such as GNU make's -j option). Doing so may cause
  errors.
