Changes to Tcl between r10 and r11

'''Tool Command Language'''

Tcl is a dynamic programming language that is available on many platforms.  Tcl is very flexible and consistent.  For example, you can re-implement the "if" command within Tcl (see [Reimplementing the If Statement in Tcl])

Tcl's flexibility makes it easy to implement other languages directly in Tcl, see for example:
   * [LOLCODE in Tcl]
   * [HTML in Tcl]

   * [Tcl Quine]
(blank line)
