The Tcl extension module gives access to the Tcl library
with functionality and interface similar to the C
functions of Tcl. In other words, you can
create Tcl interpreters
The Tcl interpreters so created are Perl objects
whose destructors delete the interpreters cleanly
when appropriate.
execute Tcl code in an interpreter
The code can come from strings, files or Perl
filehandles.
bind in new Tcl procedures
The new procedures can be either C code (with
addresses presumably obtained using dl_open and
dl_find_symbol) or Perl subroutines (by name,
reference or as anonymous subs). The (optional)
deleteProc callback in the latter case is another
perl subroutine which is called when the command
is explicitly deleted by name or else when the
destructor for the interpreter object is
explicitly or implicitly called.
Manipulate the result field of a Tcl interpreter
Set and get values of variables in a Tcl interpreter
Tie perl variables to variables in a Tcl interpreter
The variables can be either scalars or hashes.
