# This init file redefines the "unknown" command so that
# it will use pattern-matching like that of Xt for commands.
# This allows use of shorter widget names e.g. *myBtn
# Commands that are not abbreviations this way are passed
# onto the old unknown. To allow for a stack of "unknown"
# commands, unknowns are relabelled unknown.old, unknown.old.old, etc
#
