What is the tcl library path?

[José Isaías Cabrera]

Greetings.

I am working with SQLite, and I am trying to build the SQLite library with TCL support. The SQLite folks asked me the path of the TCL library which I have to idea how to identify. Is there a command that would display the path of the working TCL library. This is the tcl version cygwin installs:

jcabrera@jicman ~/b/sqlite/dbug/SQLite-f97f9944
$ tclsh
% puts $tcl_version
8.6
%

Any help would be greatly appreciated. Thank you.
