Starting "inferior-tcl" buffer w/commands included

[gamename]

Hi,

There are certain commands I often use when I'm in the inferior-tcl
buffer (debug, displays, etc).  Is there a way to auto-magically set
these in my inferior buffer at startup.  I'm thinking there must be a
way to automatically include (or "source" in tcl parlance) a file with
these commands already defined.

Any ideas?

Thanks,
