# The focus of this file is testing the ability of the database to
# uses its rollback journal to recover intact (no database corruption)
# from a power failure during the middle of a COMMIT.  The OS interface
# modules are overloaded using the modified I/O routines found in test6.c.  
# These routines allow us to simulate the kind of file damage that 
# occurs after a power failure.
