   4 # These specs are difficult because the values may vary
   5 # depending on platform or other configuration options.
   6 # However, the specs are valuable in that they will ensure
   7 # that rbconfig loads and contains required values.
   8 #
   9 # The Config entries fall into two general categories:
  10 # 1) the static-value entries; and 2) the configured-
  11 # value entries. For the second one, the specs check
  12 # only for the existence of a key.
