Exercise: Tk - a GUI for a grep-like application

The GUI should accept:

  • A filename, a wilde-card expression, maybe a dirctory name (and then a flag to recurse or not).

  • A regular expression.

  • Various flags for regex.

  • Then it should display the lines that match the expression in the selected files.
