Searches for tcl (tclsh and wish) in PATH and checks which version is installed. The macro bails out if either tcl is not found or the minimum version is not satisfied, unless minimum version is "0".



This checks for tcl and if not found, exits with an error. If found, it prints tcl path and version number.


Checks for tcl and exits with an error if its not found or the version is below 8.0.
