This is the file that gets printed when the user runs "make help",
starting just after the "help-starts-here" line.

help-starts-here

all
	The usual default; builds everything but doesn't run the
	tests.

check (or tests)
	Runs the standard set of tests.

test
	Runs one test.  Use like this:
		make test t=wcsmbs/test-wcsnlen
	Note that this will rebuild the test if needed, but will not
	rebuild what "make all" would have rebuilt.

build-math-static-tests
	Enable extra math tests for static linking.  Use like this:
		make test t=math/test-float-exp10-static build-math-static-tests=yes

--
Other useful hints:

builddir$ rm testroot.pristine/install.stamp
	Forces the testroot to be reinstalled the next time you run
	the testsuite (or just rm -rf testroot.pristine)
