-// ClassDB - code to manipulate class databases.

-// It would have been easier to write this in Lua, but since every
-// lua module in the system depends on it, it's safer to have it
-// preloaded before we even open any of the lua files.
 //
+// The source database is a lua table that maps filenames
+// to file info.  The source database is stored in the registry.
+//
+// In the source database, the keys are filenames, and the values
+// are tables containing the following fields:
+//
+//     name: filename as a string
+//     fingerprint: file modification, file length, as a string
+//     code: the entire contents of the source file as a string
+//     loadresult: a lua closure, or, an error message
+//     sequence: the position of the file in control.lst
