+Introduction
+------------
+
+Tweaking...
+
+You can disable whole classes of algorithms on the command line with the LTC_NO_* defines.  From there you can manually turn on what you want to enable.  
+
+The following build with GCC 3.4.3 on an AMD64 box gets you AES, CTR mode, SHA-256, HMAC, Yarrow, full RSA PKCS #1, PKCS #5, ASN.1 DER and MPI in 
+roughly 80KB of code.

+Neato eh?
