## Override the definition from Automake to generate a log file with
## failed tests.  It also supports parallel make checks.
##
## This file provides special support for "unit tests", that is to
## say, tests that (once run) no longer need to be re-compiled and
## re-run at each "make check", unless their sources changed.  To
## enable unit-test supports, define LAZY_TEST_SUITE.  In such a
## setting, that heavily relies on correct dependencies, its users may
## prefer to define EXTRA_PROGRAMS instead of check_PROGRAMS, because
## it allows intertwined compilation and execution of the tests.
## Sometimes this helps catching errors earlier (you don't have to
## wait for all the tests to be compiled).
##
## Define TEST_SUITE_LOG to be the name of the global log to create.
## Define TEST_LOGS to the set of logs to include in it.  It defaults
## to $(TESTS:.test=.log).

## We use GNU Make extensions (%-rules), and override check-TESTS.
