Learning Tcl/Tk the Hard but Useful Way

Hello,
I'm an experienced programmer, and I'd like to learn Tcl/Tk the hard
but useful way, that is to say, to solve real work problems. I have a
need to automate file download, given the file's url, to unzip the
file to a local Windows folder, and to send an email to me that it's
been done. I also need to schedule it to run daily, but this can be a
Windows scheduler issue. I find it hard to find the bits and pieces I
need to put together. Anyone who can point me to the right direction?
An example may be. Thanks.

check out man pages and http://wiki.tcl.tk in general and specifically for:

ftp and http package
for downloading things (you weren't specific on how the
downloads were being served)
exec command
will allow you to invoke the unzipping of a file

smtp and mime packages
to send email

Tcl is great, but something like that would be a very short shell
script:

wget http://..............
unzip $filename
echo "$filname downloaded" | mail -s "$filename downloaded" your@address.com

You could use cygwin, most likely.

Wow! A simple command for each task at the level of abstraction I'm
comfortable, I can't ask for more. Thanks all.
