+sbase test suite
+================
+
+Test suite for sbase.
+
+Tests for each tool live in a directory in t/ named after the tool. Tests for
+ed live in t/ed.
+
+t/run runs all tests.
+
+t/run_t runs all tests for one tool. E.g. t/run_t t/ed runs all tests for ed.
+
+Tests names must match [0-9][0-9][0-9][0-9] and have the executable bit set.
+
+Tests return 1 if the test failed and return 2 in case of any other error.
