// Package visa wraps National Instruments VISA (Virtual Instrument Software
// Architecture) driver. The driver allows a client application to communicate
// with most instrumentation buses including GPIB, USB, Serial, and Ethernet.
// The Virtual Instrument Software Architecture (VISA) is a standard for
// configuring, programming, and troubleshooting instrumentation systems
// comprising GPIB, VXI, PXI, serial (RS232/RS485), Ethernet/LXI, and/or USB
// interfaces.
//
// The package is low level and, for the most part, is one-to-one with the
// exported C functions it wraps. Clients would typically build an instrument
// specific driver around the package but it can also be used directly.
