Force Reread of "local variables:"

[Tennis Smith]

Hi,

Anyone have code that will force a re-read of a "local variables:"
sections in a file?

I have several files with this sort of data appended at the bottom:

# -----------------------------------------------------------------------------
# ;;; Local Variables: ***
# ;;; mode: tcl ***
# ;;; project: SUMCHK ***
# ;;; End: ***

If I change the "project" var in the file, is there a way to have
emacs reread this?

TIA,
-Tennis
