 dbfp is a tool that will scan a sqlite database and generate a fingerprint.
-The fingerprint is basically the database schema.
+The fingerprint will uniquely identify the database.
+The fingerprint consists of the database schema, the sql table create statements, 
+  md5 calculations, and file meta-data.
 The fingerprint is stored to disk in JSON format.
 
+The fingerprint can be used to identify unknown databases from random paths or recovered from deleted space.
+The fingerprint can be used for historical comparisons to see what has changed in a new version of an application.
