-// FEATURE: This is just a quick hack, it is really ugly and broken
-
-// FEATURE: Cache based on org.ibex.util.Cache
-// FEATURE: Base64 encode some id to form package name
-// FEATURE: Timestamped cache entries, requests carry minimum timestamp
-// NOTE: Need to handle binaries spanned accross many classfiles
