New in 0.0.7
* March 29, 2000
* Added support for RedHat package building contributed by Habibie 
  <habibie@MailandNews.com>
* Added gdbm to SimGear.  Many systems will already have gdbm installed so
  it is only built if it doesn't already exist on the user's platform.
  gdbm is a set of database routines that use extendible hashing and works
  similar to the standard UNIX dbm routines.  This guarantees the availability
  of gdbm to any application that uses SimGear.

  Vine and Ed Williams
