@majorheading Synopsis

@smallexample
AX_PROG_TCL([min-version])
@end smallexample

@majorheading Description

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".

Example:

@smallexample
 AX_PROG_TCL
@end smallexample

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

@smallexample
 AX_PROG_TCL([8.0])
@end smallexample

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