QOTW:  "The key to doing sane parsing is often the negative lookahead
assertion." -- Donal K. Fellows
    http://groups-beta.google.com/group/comp.lang.tcl/msg/b8a9d0c730c75d98

"[U]nlike other lang[uage]s ... if you wonna know the internals [of
Tcl], you can." -- shishini, yet another admirer of the lucidity of
the source implementation of Tcl


POTW:  Michael Kirkham's TclMilter expands Sendmail scripting beyond the C
that Sendmail's maintainers find natural (and the other high-level language
bindings that antedate it).

    Andreas Leitgeb and Darren New explain good style in use
    of [upvar] and [return].

    A fully-capable PocketPC port would take only a finite amount more
    effort.

    The options database is so handy as to inspire generalization beyond
    its usual widgetry employment.  David Bigelow has experience and a
    tip for working in this area, along with incidental praise of SNIT.

Thanks to Arjen Markus for his report from the Wiki(s):
  A potpourri of subjects again, but that is not unusual
  on the Tclers' Wiki!
  
  Little tools
  - Start your favourite programs from this little menu ...
    <http://wiki.tcl.tk/14135>
  
  - Need to justify text to the left or the right and you do 
    not want to remember the [format] command? Maybe this little
    package is what you are looking for ... <http://wiki.tcl.tk/11554>
  
  - If the name "code 39" does not mean anything to you, perhaps 
    "barcode" does. A practical tool to generate barcodes ...
    <http://wiki.tcl.tk/9335>
  
  Funny things
  - A starry night on your screen, so you do not have wait too
    long and have no problems with clouds ... <http://wiki.tcl.tk/14140>
  
  - Here is a bit of math: draw a curve defined by its parametric
    equations - <http://wiki.tcl.tk/14130>
  
  Promises 
  - Getting the message across - well, on the same machine anyway
    - this system is geared to data analysis - <http://wiki.tcl.tk/3317>
  
  - Ah, printing! The eternal subject that causes so much debate ...
    <http://wiki.tcl.tk/2496>
  
  - Will Tcl 8.5 have _proper_ integers at last? Many people want
    to get rid of the annoying limitation of ordinary computer
    arithmetic - <http://wiki.tcl.tk/10942>
    

Everything Tcl-related you want is probably one or two clicks away in these
