- * The following code handles the storage of PKCS 11 modules used by the
- * NSS. For the rest of NSS, only one kind of database handle exists:
- *
- *     SFTKDBHandle
- *
- * There is one SFTKDBHandle for each key database and one for each cert 
- * database. These databases are opened as associated pairs, one pair per
- * slot. SFTKDBHandles are reference counted objects.
- *
- * Each SFTKDBHandle points to a low level database handle (SDB). This handle
- * represents the underlying physical database. These objects are not 
- * reference counted, and are 'owned' by their respective SFTKDBHandles.
