# AT_CHECK_EUNIT(MODULE, SPEC, [ERLFLAGS], [RUN-IF-FAIL], [RUN-IF-PASS])
# ----------------------------------------------------------------------
# Check that the EUnit test specification SPEC passes. The ERLFLAGS
# optional flags are passed to the Erlang interpreter command line to
# execute the test. The test is executed from an automatically
# generated Erlang module named MODULE. Each call to this macro should
# have a distinct MODULE name within each test group, to ease
# debugging.
# An Erlang/OTP version which contains the eunit library must be
# installed, in order to execute this macro in a test suite.  The ERL,
# ERLC, and ERLCFLAGS variables must be defined in atconfig,
# typically by using the AC_ERLANG_PATH_ERL and AC_ERLANG_PATH_ERLC
# Autoconf macros.
