## This package sets up a mechanism for diagnostic assertions at GAP
## level.
##
## These tests are controlled by a single global assertion level settable
## and readable by user functions SetAssertionLevel( <level> ) and
## AssertionLevel().
##
## We store this level in the "unpublished" global variable
## CurrentAssertionLevel
##
## Assert itself is implemented in the kernel, see the scanner, reader,
## intrprtr, coder and stats packages
##
## This file is the GAP level implementation part of that package
##
