hi there Dr!
The answer to your question is "yes".. an eggie can easily perform this task..
But learning TCL is not so easy.. unfortunately.. TCL is NOT .mrc and the 2 are completely
different!
Luckly, theres plenty of resources out there that can help you along.. You can visit
http://www.tcl.tk to get yourself a good start.
Like you, I had to learn TCL "to get the job done" and I have come along.. but, I'm in no ways, anywhere as good as Nml, Speechles, FZ, Caesar, and a few others on here (this is the place for the top minds for TCL!).
My advice to you is to make sure you have a fresh mind- get plenty of sleep and do NOT find yourself in a hurry to learn it.. because that won't happen!
look for some example scripts.. one's that tell you and/or explain what they do.. and try to understand the sintax.. TCL does have a "steep learning curve" but its not impossable to pick up (PHP is easier to learn) and admittedly, some of the resources are "not friendly to the beginner", but, if you take your time, and understand the sintax/basics.. you'll be writing your own scripts in no-time.
One of the things I like about TCL is, theres a few ways you can do things.. not saying that these ways are the "best" ways or most-efficient (that comes with experience) but nonetheless, it still makes you feel good when it works!
I hope this post helps you feel ready for the task ahead
