REVISION HISTORY
Description: Renamed BytesThisFrame to WmfBytesPerFrame, changed its type
from 'const short' to 'const int'. Added If2BytesPerFrame
table for IF2 input format. Updated copyright year and I/O
definition sections, and added reference document for IF2.
Description: Renamed WmfBytesPerFrame to WmfDecBytesPerFrame, and
If2BytesPerFrame to If2DecBytesPerFrame.
Description: Added #ifdef __cplusplus and removed "extern" from table
definition.
Description: Put "extern" back.

RESOURCES USED
When the code is written for a specific target processor the
the resources used should be documented below.
STACK USAGE: [stack count for this module] + [variable to represent
stack usage for each subroutine called]
where: [stack usage variable] = stack usage for [subroutine
name] (see [filename].ext)
DATA MEMORY USED: x words
PROGRAM MEMORY USED: x words
CLOCK CYCLES: [cycle count equation for this module] + [variable
used to represent cycle count for each subroutine
called]
where: [cycle count variable] = cycle count for [subroutine
name] (see [filename].ext)
