Well, emacs, I suppose.  Texinfo is a fairly simple text based

Unfortunately, I have a hard time understanding this.

Is pstruct a standard perl module?  If not, does this dump information
actually have anything to do with Perl?

Can we specify this more formally?  Or is this some sort of Perl
syntax?  (It's been many years since I've used Perl).
