+# Test using the testsuite for the gc Go compiler.  In these tests the

+#   G   The name of the compiler
+#   L   The name of the linker
+#   F   The basename of the test
+#   D   The directory of the test.
+#
+# Typical command lines:
+# // $G $D/$F.go && $L $F.$A && ./$A.out
+# // $G $D/$F.go && $L $F.$A || echo BUG: known to fail incorrectly
+# // $G $D/$F.go && echo BUG: compilation succeeds incorrectly

+This directory is an exact copy (except for this file) of the Go
+testsuite from the test subdirectory of http://code.google.com/p/go.
+This is here so that we run the same tests as the gc Go compiler.  We
+do not, however, run the tests in the same way.  The gc compiler uses
+the run shell script in this directory.  For gccgo, we use the file
+go-test.exp in the parent directory to run the tests in gcc's usual
+DejaGNU test harness.
