Oh, ok.  I'll have a look at that
discussion.

Yes, I have seen this discussion.  But
I'm still
...
...
confused: are commas
...
a problem in tcl?  If not, I still don't
understand the problem (see
...
attached).
<file.pd><parser.pd>
Tcl's not the problem, its Pd's parser.  It
interprets
...
...
commas as a
separator between messages.  Since there
isn't an
...
...
escape mechanism, it
means handling commas, semi-colons, etc. is
difficult
...
...
unless you are
wanting the behavior of Pd's parser.
If we use commas as the delimiter for individual
tags, then
...
...
just
removing the commas means you don't know if you
have
...
...
multi-word tags
or just single word tags.  So if you have:
 tags - frequency

modulation, synth
...
...
and its parsed as:
 tags frequency modulation

synth
...
...
then key information is lost.
Ok. (see attached)
Works for me!  Frank will be happy. So let's use
comma-separated tags
and see what happens...
So what kinds of tasks do you want Pd to do with these META comments?
If you already have specific ideas in mind (or have written about them
already some place), let me know and I'll try to put together some
patches.
I think they'll be very useful for searching for an object that does

what you want, or organizing the help patches into some kind of

navigatable hierarchy.  Perhaps people will think of other uses as well.
...
I'm also getting close to the finishing refactoring the help patches
in the reference folder.  What should I do with them when I'm

finished?
Attach a zip file to the list?
This sounds great! To start with, try posting some to the list, or

putting the zip on puredata.info and post a link.
