32	32	The database uses a read-only, memory-mapped data file to ensure that
33	33	applications cannot corrupt the database, however, this means that keys and
34	34	values returned from Bolt cannot be changed. Writing to a read-only byte slice
35		will cause Go to panic. If you need to work with data returned from a Get() you

	37	Keys and values retrieved from the database are only valid for the life of
	38	the transaction. When used outside the transaction, these byte slices can
	39	point to different data or can point to invalid memory which will cause a panic.
