+# Note:
+# 
+# This test checks the "direct linking to a dll" functionality.
+# 
+# The test has 7 stages:
+# 
+# 1. compile and link a test dll with ".dll" extension.
+#
+# 2. compile and link a test dll with ".sl" (i.e. != ".dll") extension.
+#
+# 3. compile and link a client application linking directly to the ".dll" dll built in 1.
+#    This should produce no errors.
+#
+# 4. compile and link a client application linking directly to the ".sl" dll built in 2.
+#    This should produce no errors.
+#
+# 5. compile and link a client application linking directly to a symlink into 
+#    the ".dll" dll built in 1.
+#    This should produce no errors.
+#
+# 6. compile and link a client application linking directly to a symlink into 
+#    the ".sl" dll built in 1.
+#    This should produce no errors.
+#
+# 7. run the produced executables
+
+# This test can only be run on PE/COFF platforms.
