NAME
IO::Digest - Calculate digests while reading or writing SYNOPSIS
use IO::Digest; # Get a Digest::MD5 object that takes input while $fh being written or read $iod = IO::Digest->new ($fh, 'MD5'); print $fh "fooo"; print $iod->hexdigest DESCRIPTION
This module allows you to calculate digests while reading or writing file handles. This avoids the case you need to reread the same content to compute the digests after written a file. TEST COVERAGE

NAME
PerlIO::via::symlink - PerlIO layers for create symlinks SYNOPSIS
open $fh, '>:via(symlink)', $fname; print $fh "link foobar"; close $fh; DESCRIPTION
The PerlIO layer "symlink" allows you to create a symbolic link by writing to the file handle. You need to write C"link $name" to the file handle. If the format does not match, "close" will fail with EINVAL. TEST COVERAGE
