  Mr. Avery Lee once told us that his software `VGAPaint 386' has a BIG bug,
  because it does not restore some interrupt vectors on exit correctly.

  We found it very painful to use DOS' DEBUG for monitoring the interrupt
  vector table. So we wrote DIVT to make life a little easier.

  DIVT directly reads the interrupt vector table at memory address 0:0 and
  displays each entry in the following way:

    Int 00h: 0139:108A
    Int 01h: 0070:06F4
    Int 02h: F000:E2C3
    .
    .
    .
    Int FEh: 0201:0008
    Int FFh: FF00:292C

  DIVT does not support any command-line options, so just execute `DIVT.COM'
  to display the interrupt vector table.

  It might be a good idea to pipe DIVT's output to DOS' MORE command or into a
  file: "divt | more" or "divt > divt.log". Otherwise output will scroll out
  of the visible screen area.

  To compare two DIVT outputs use DOS' FC command: "fc divt1.log divt2.log".
