By "port" do you mean you are adding a new target to GDB?  Or are you
porting it to a new host OS? Or both?

Which sources are you starting from?

You should have gdb/gdbtk/library/help/debug.html.  Take a look at
that.  Set the environment variable "GDBTK_DEBUG" before running insight
then look for errors in the debug window.  Add debug statements into the
tcl source as necessary.

See gdb/gdbtk/README for more information.

Just the internal debug window.  It can trace or display the output of tcl debug statements.

Nothing more than the README file and inline comments.
