libtie-persistent-perl - 1.00-2.1 main

Tie::Persistent makes working with persistent data real easy by using the tie
interface. It works by storing data contained in a variable into a file (not
unlike a database). The primary advantage is speed, as the whole datastructure
is kept in memory (which is also a limitation), and, of course, that you can
use arbitrary data structures inside the variable (unlike DB_File). Note that
it is most useful if the data structure fits into memory.
