+
+    Converts output from NEI dump files into a format which can be used by
+    Crafting Guide. In particlar, this script looks for the "Item Panel" dump
+    both in PNG and CSV formats and assumes they contain all the data for the
+    target mod.
+
+    Unfortunate, NEI doesn't generate enough information to fill in all the
+    recipes for each item: only their names. Once this script has converted the
+    data, you will need to manually enter the missing content.
+
+    <source>    :    the "dumps" directory where NEI dropped its content
+    <target>    :    the mod version directory where the finished files should
+                     be placed
