How do I convert v5 hatches to v6 or later?

The following instructions refer to VCADD6, but they apply to all newer versions of VCADD.  Substitute your version for VCADD6

1) Shutdown VCADD6.
2) Go to the VCADD6 System folder and rename Hatches.vchat to
Hatches_default.vchat (or similar).
3) Copy your v5 hatches.hat file to the VCADD6 System folder.
4) Restart VCADD6.

When v6 starts, it will see that hatches.vchat is missing and will convert
the v5 hatches.hat to the new format. If there is no hatches.hat available,
then v6 will just create a default hatches.vchat.
