+Testing Guidelines
+~~~~~~~~~~~~~~~~~~
+
+It's considered good form to test your new feature before you submit a patch
+to the mailing list, and especially before you commit a change to CVS. Here
+are some guildlines on testing your changes.
+
+ - Always test busybox grep against GNU grep and make sure the behavior /
+   output is identical between the two.
+
+ - Try several different permutations and combinations of the features you're
+   adding and make sure they all work. (Make sure one feature does not
+   interfere with another, etc.)
+
+ - Make sure you test compiling against the source both with the feature
+   turned on and turned off in Config.h and make sure busybox compiles cleanly
+   both ways.
