Dialyzer's PLT format

[Guy Wiener]

Hello everyone,
I want to re-use the Dialyzer's PLT files for some tools I'm developing,
similarly to what the Typer does. I tried to look it up, but the format of
the PLT file is not in the documents.
How can one re-use a PLT file? Is it a Mnesia DB, or something similar? Is
the format or schema documented somewhere?

Btw, thanks for the great answers about these tools fro my previous
questions.

Thanks in advance,
  Guy Wiener.
