##
## 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().
##
## The actual format of the check is Assert( <level>, <test> [, <message> ])
## which is equivalent to either:
##
## if AssertionLevel() >= <level> and <test> then
## Error("Assertion <test> failed");
## fi;
##
## or
##
## if AssertionLevel() >= <level> and <test> then
## Print( <message> );
## fi;
##
## depending on the number of arguments.
##
## Assert is a keyword implemented in the kernel
##
## This file is the declarations part of that package
