+CrackLib is a library containing a C function (well, lots of functions
+really, but you only need to use one of them) which may be used in a
+"passwd"-like program.
+
+The idea is simple: try to prevent users from choosing passwords that
+could guessed by "Crack" by filtering them out at the source.
+
+An example of its use can be located in the SAMBA examples directory.
+The crackcheck program included with SAMBA will use the library to ensure
+that the user doesn't pick a weak password.
+
+A larger dictionary can be found here
