My reading of Tcl/Tcl::Tk indicates it creates a tcl interpretter.

1. Does this interpretter run in the same process as perl, or
a subprocess ?

2. How does it behave wrt PAR, perl2exe, or PerlApp (ie, bundling
into a single executable for distribution) ? Obviously, I'd need to
bundle tcl + tcl/tk stuff into the executable; I'm wondering if
Tcl::Tk will be able to find the tcl + tcl/tk pieces in that
environment ?

3. Much of the tcl.tk website seems to be undergoing repair...is
there an alternate link to enumerate all available widgets ?
