Pretty close (should've included it)
Do I need the colons before the field names?  I'm not doing that now.

Here's a couple table's worth:
---
  -
    name: PM_Static_SettingsDB
    file: settings.dbf
    fdel: false
    dnoc: false
    fields:
      - key      CHAR 254
      - redir    CHAR 254
      - admin    CHAR 254
      - hidehelp BOOL
      - last_tab CHAR 50

    indexes:
      -
        file: cats.mvx
        expr: PM_Static_catsDB.d.cat_id
        flag: nounique, ascending
  -
    name: PM_Static_KeysDB
    file: keys.dbf
    fdel: false
    dnoc: true

    fields:
      - name CHAR 50
      - value NUMBER
    indexes:
      -
        file: keys.mvx
        expr: PM_Static_KeysDB.d.name
        flag: nounique, ascending

I'll give that a shot, was wondering if there was a way to auto create
objects from the YAML load, but yeah, I could loop through them and do
it that way.  I'll see how it goes.
