<P class="first-line-indented">These tools works the same way as their non

_MESSAGE form. The only difference is that instead of generating an error/confirm

message these tools use the supplied one.</P>

<P class="first-line-indented">The first parameter should be boolean

predicate value that gets validated. The second parameter is the

message logged in case of check failure. The message argument can be of

any type supporting the operator <<(...) or can be a result of concatenations

using the operator <<(...).</P>
