.SH DIAGNOSTICS

When invoked incorrectly, a debug message will be printed and the program will
exit with the appropriate
.BR sysexits.h (3)
error code.
.\"
.SH RATIONALE 

The 
.BR test (1p)
utility contains functionality that was broken out into separate programs. Thus,
the scope of this program is narrower than it. Notably, the
.B -h
option is now invalid and therefore shows usage information instead of being an
alias to the modern
.B -L
option.
