+# This set of tests verifies various requirementgs relating to correct
+# (and incorrect) syntax of shell input
+#
+# There is no intent in these tests to verify correct operation
+# (though that sometimes cannot be separated from correct parsing.)
+# That is (or should be) verified elsewhere.
+#
+# Also, some very basic syntax is tested in almost every test
+# (they cannot work without basic parsing of elementary commands)
+# so that is also not explicitly tested here.
+#
+# Similarly word expansion, field splitting, redirection, all have
+# tests of their own (though we do test parsing of redirect ops).
+#
+# Note that in order to test the basic facilities, other shell operations
+# are used - a test failure here does not necessarily mean that the
+# operation intended to be tested is faulty, just that something is.
