NAME
Mnet::Tee - Redirect stdout and stderr to a file
SYNOPSIS
# use this module on it's own
use Mnet::Tee;
Mnet::Tee::file($file);
# or use with command line options
use Mnet::Tee;
use Mnet::Opts::Cli;
my $cli = Mnet::Opts::Cli->new;DESCRIPTION
Mnet::Tee can be used to capture all stdout and stderr output from the calling script, saving the combined output to a file.
The variables stdout and stderr can be imported from this module to use for output that should not be captured by the Mnet::Tee module.
Note that output captured by this module is stored in memory during script execution. That could be a problem for scripts that generate gigabytes of stdout and/or stderr output.
The perl tie command is used to implement the functionality of this module.
