What is OSCON, and how does it relate to Tcl?

'''OSCON''' stands for '''O'''pen '''S'''ource '''Con'''ference [http://conferences.oreillynet.com/],
and they are hosted by the well-known publisher [O'Reilly] & Associates.

In the year 2001, OSCON sported a [Tcl] track. This was dubbed the
[Eighth Annual Tcl/Tk Conference] and held on July 23-27 in San
Diego, California. See http://conferences.oreilly.com/archive.html
(or ftp://ftp.oreilly.com/pub/conference/os2001/ )
for pointers to presentations and papers presented at this conference.

Before OSCON / O'Reilly, [Tcl conferences] were held by [Usenix],
and the last one under its aegide was the
[Seventh Annual Tcl/Tk Conference]
held on Feb 14-18 2000 in Austin, Texas.

Now, in 2002, the Tcl community is going its own way again,
with a conference sponsered by [ActiveState] (see the
[Ninth Annual Tcl/Tk Conference]),
to be held on September 16-20 2002 in Vancouver, Canada.

I seem to recall there was a Tcl track in 2000 as well - just
not well attended.

[AK] My recollection is that it was too near in time to the
regular conference in Austin, so less people went.
