+# Test using the testsuite for the gc Go compiler.  In these tests the
+# first line is a shell script to run.  That line expects the
+# following environment variables to be set:
+#   A   The file extension of the object file and the name of the executable
+#   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:
+# // compile
+# // run
+# // $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
+# // $G $D/$F.go || echo BUG: compilation should succeed

+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.

+	"  Now we are engaged in a great Civil War, testing whether that\n" +
+	"nation, or any nation so conceived and so dedicated, can long\n" +
+	"endure.\n" +
+	"  We are met on a great battle-field of that war.\n" +
+	"  We have come to dedicate a portion of that field, as a final\n" +
+	"resting place for those who here gave their lives that that\n" +
+	"nation might live.  It is altogether fitting and proper that\n" +
+	"we should do this.\n" +
+	"  But, in a larger sense, we can not dedicate — we can not\n" +
+	"consecrate — we can not hallow — this ground.\n" +
+	"  The brave men, living and dead, who struggled here, have\n" +
+	"consecrated it, far above our poor power to add or detract.\n" +
+	"The world will little note, nor long remember what we say here,\n" +
+	"but it can never forget what they did here.\n" +
+	"  It is for us the living, rather, to be dedicated here to the\n" +
+	"unfinished work which they who fought here have thus far so\n" +
+	"nobly advanced.  It is rather for us to be here dedicated to\n" +
+	"the great task remaining before us — that from these honored\n" +
+	"dead we take increased devotion to that cause for which they\n" +
+	"gave the last full measure of devotion —\n" +
+	"  that we here highly resolve that these dead shall not have\n" +
+	"died in vain — that this nation, under God, shall have a new\n" +
+	"birth of freedom — and that government of the people, by the\n" +
+	"people, for the people, shall not perish from this earth.\n" +
