 *     which saves highest major, minor, and micro version numbers
 *     that last used it and the highest major, minor, and micro
 *     version numbers that may use this repository.
 *
 *     If a PRCS opens a repository or entry which was last used by a
 *     higher version number than itself but still higher than the
 *     usable by field, it will print a warning and any important
 *     upgrade information and continue.  If a PRCS opens a repository
 *     or entry which is not usable, it will print an error and exit.
 *
 *     However, each time a repository is opened which is tagged at a
 *     lower version number, it looks in these arrays for upgrade
 *     functions.  the upgrade functions are grouped with a set of
 *     version numbers that it will upgrade a repository to.  They
 *     must be in order.  If PRCS opens a repository or entry with an
 *     old tag, it will apply all applicable upgrades (with the
 *     users's consent).  */
