# #
# This is what the basic structure of your $REF_DIR should look like: Subdirectories for each subject, and then another set of subdirectories for the part of the #
# subject you want to reference. And in the second subdirectory, an index.html file. #
+#
+# To use ref, you do the ref command followed by the sugject and the sub-subject as arguments. For instance:
+#
+# ref bash array
+#
+# Would open the bash/array/index.html file.
+#
+# To list your references, you would do the ref ls command, optionally followed by a subject. For instance:
+#
+# ref ls
+#
+# Would give me:
+#
+# ruby bash
+#
+# And:
+#
+# ref ls bash
+#
+# would output:
+#
+# array
+# select
