=head1 NAME

paymentech-upload

paymentech-upload - Transmit a payment batch to Chase Paymentech via SFTP.

=head1 SYNOPSIS

  paymentech-upload [ -a ] [ -v ] [ -t ] user batchnum

=head1 DESCRIPTION

Command line tool to upload a payment batch to the Chase Paymentech gateway.
The batch will be exported to the Paymentech XML format, packaged in a ZIP 
file, and transmitted via SFTP.  Use L<paymentech-download> to retrieve the 
response file.

-a: Send all open batches, instead of specifying a batchnum.

-v: Be verbose.

-t: Send the transaction to the test server.

user: freeside username

batchnum: pay_batch primary key

=head1 BUGS

Passing the zip password on the command line is slightly risky.
