NAME

Archive::Parity - makes parity file; recover files.

USAGE

use Parity;

to make a parity file from a list of files: Parity::do_parity (out_filename, filename1, filename2, filename3);

to recover a lost file: use the same command, placing the lost file name in front of the list: Parity::do_parity (filename1, out_filename, filename2, filename3);

The parity file must have a ".par" extension.

TODO

object interface. register module Archive::Parity. try not to overwrite outfile; do not allow repeated filenames. save filename; check errors. memory operation for small files. make, test. Test with different chunk sizes. check_parity just to check if everything is ok.
