WineASIO provides an ASIO to JACK driver for WINE. ASIO is the most common
Windows low-latency driver, so is commonly used in audio workstation
programs.

This requires wine and jack-audio-connection-kit.

To build the package, you will need the file "asio.h" from the Steinberg
ASIO SDK, version 2.1 or greater. This file must be downloaded from
http://www.steinberg.net/en/company/developer.html and copied to the
directory containing the SlackBuild.

After installing the package, each user who will use wineasio must run
the command "regsvr32 wineasio.dll". This must be done as the user(s),
not as root. This only needs to be done once per user.

This can't be built on a stock Slackware64 system, since it requires
32-bit Wine. It may (or may not) be possible to build on a 64-bit multilib
system; let me know how it goes.
