/*
 * acqdrv - acquiring driver client.
 *
 * Starts ONE global transaction (tpbegin), fires the ACQUIRE -> RECONCILE ->
 * SETTLE chain via a single tpcall("ACQUIRE"), then tpcommit (or tpabort when
 * the 4th arg is "abort", to prove XA rollback).
 *
 * Usage: acqdrv [merchant] [amount] [bizdate YYYY-MM-DD] [abort]
