+This new structure, notmuch_crypto_t, keeps all relevant crypto\r
+contexts and parameters together, and will make it easier to pass the\r
+stuff around and clean it up. The name of the crypto context inside\r
+this new struct will change, to reflect that it is actually a GPG\r
+context, which is a sub type of Crypto context. There are other types\r
+of Crypto contexts (Pkcs7 in particular, which we hope to support) so\r
+we want to be clear.\r
+\r
+The new crypto.c contains functions to return the proper context from\r
+the struct for a given protocol (and initialize it if needed), and to\r
+cleanup a struct by releasing the crypto contexts.\r
