A tool graph chunk can occur either as a top-level form or as a subchunk of a segment form.
RIFF( 'DMTG'
[<guid-ck>] // GUID for tool graph
[<vers-ck>] // Optional version info
[<UNFO-list>] // Name, author, copyright info, comments
<toll-list> // List of tools
)
For the first three elements, which are optional, see Common Chunks.
The main and only required part of the tool graph chunk is the tool list:
<toll-list> -> LIST( 'toll'
<DMTL-form>...
)
For more information on the <DMTL-form> chunk, see Tool Form.
