# debugger rescue nil is required (ha ha) because, if
# you require ruby-debug, the debugger method will be
# defined *before* all debugger components are loaded
#

# Please note that, because this method is defined in
# Object, caller(0) will contain [$0,$0], thus you'll
# have to step inside the original require method and
# then call caller(0).
