Maintenance is still done by the Author, | whilst the perl5-porters ensure that no change to the Perl internals | can break the version of Storable distributed with it. +======================================================================= The Storable extension brings persistency to your data. You may recursively store to disk any data structure, no matter how complex and circular it is, provided it contains only SCALAR, ARRAY, HASH (possibly tied) and references (possibly blessed) to those items. At a later stage, or in another program, you may retrieve data from the stored file and recreate the same hiearchy in memory. If you had blessed references, the retrieved references are blessed into the same package, so you must make sure you have access to the same perl class than the one used to create the relevant objects. There is also a dclone() routine which performs an optimized mirroring of any data structure, preserving its topology. Objects (blessed references) may also redefine the way storage and retrieval is performed, and/or what deep cloning should do on those objects. To compile this extension, run: perl Makefile.PL [PERL_SRC=...where you put perl sources...] make make install There is an embeded POD manual page in Storable.pm.
