How do I query Tcl about its version?

Question

There must be an easy way to do this, but I can't find it.

What command can I run within Tcl to get it to introspect and report the version of itself that is running?

in addition to other options, you can use:

puts $tcl_version

This has the advantage of working for comically old versions of tcl.

This only gives you the major version (8.5) but not the full version (8.5.7) – Carlos Tasada Sep 16 '09 at 14:46
