The Inline::Tcl module allows you to put Tcl source code directly "inline" in a Perl script or module. A Tcl interpreter is loaded and the Tcl code is interpreted, then Perl asks the Tcl interpreter which global procedures have been defined. Those functions are made available to your Perl program as if they had been written in Perl. The process of interrogating the Tcl interpreter for globals only occurs the first time you run your Tcl code. The namespace is cached, and subsequent calls use the cached version.
