At several places in VMoo you can use Tcl scripts to extend VMoo.
VMoo uses the official Tcl implementation for its scripting support, so for language reference you can use the normal Tcl documentation.
VMoo extends the Tcl language by several commands of its own.
To start the documentation proces, I will list the most commonly used keywords below.
When installed without extensions, VMoo runs one top level interpreter with per world a [safe interpreter]. With the increase interpreter permissions script you can increase the privileges of the world interpreter to an unsafe interpreter.
