+jack-tools includes a utility called "jack-lxvst", which is a host for
+Linux native VST plugins.
+
+For licensing reasons, the VST headers (copyright Steinberg) cannot
+be included in this SlackBuild. If you need jack-lxvst, you'll have to
+register as a developer at https://www.steinberg.net/ and download the VST
+developers' kit from there. You want version 2.x of the dev kit (which may
+no longer be available; not sure if version 3.x works with jack-lxvst). Once
+you've downloaded the files and extracted them, do one of these things:
+
+- Copy or symlink the files aeffect.h and aeffectx.h to the jack-tools
+  directory (the one that contains jack-tools.SlackBuild).
+
+- Or, export VST_HEADERS=<path> in the environment before running the
+  SlackBuild. <path> is the directory that contains the files aeffect.h
+  and aeffectx.h. Example: export VST_HEADERS=/usr/local/include/VST
+
+If all went well, when you install the jack-tools package, the description
+will say "This package was built WITH Steinberg Linux VST support". Just
+to be on the safe side, do not redistribute the package. I'm not a lawyer
+and I'm not sure whether Steinberg's license would allow redistribution
+of a compiled binary using the VST headers.
+
+If you did the above but the build fails to compile, you might be using
+the wrong version of the VST headers. This would be a problem for upstream
+(the actual author of jack-tools) to fix, so report it there.
+
+The above only has to be done if you actually need jack-lxvst. If you
+don't know whether you need it, read this FAQ:
+
+Q: What is VST?
+A: If you don't know, you don't need jack-lxvst, and you can stop
+   reading now.
+
+Q: What is a Linux native VST?
+A: The vast majority of VST plugins (effects and instruments) are
+   distributed as Windows executables (or DLLs). A Linux native VST is a
+   Linux executable (or shared library), either distributed as source and
+   compiled by the user, or (more often) as a precompiled binary. Linux
+   native VST plugins are pretty rare, although they do exist.
+
+Q: What is jack-lxvst?
+A: jack-lxvst is a standalone host for Linux native VSTs. If you don't
+   use Linux native VSTs, you don't need jack-lxvst.
+
+Q: I want to use Linux native VST plugins in my DAW, which has Linux
+   native VST support. Do I need jack-lxvst?
+A: No. If your DAW supports Linux native VST plugins, you don't need a
+   separate host for them (such as jack-lxvst).
+
+Q: I have this Windows VST plugin I want to use on Linux, do I need
+   jack-lxvst?
+A: No. jack-lxvst is only for Linux native VST plugins. For Windows VSTs,
+   try wineasio. Ardour can also be built with Windows VST support,
+   using WINE. Whatever solution you find for Windows VSTs on Linux
+   will pretty much have to involve WINE somehow.
+
+Q: I have a Linux native VST I want to use with my DAW, but my DAW
+   doesn't have VST support. Can I use jack-lxvst for this?
+A: Yes. This is the intended use for jack-lxvst.

 jack\-udp is a UDP audio transport mechansim for JACK\&. The send mode reads signals from a set of JACK input ports and sends UDP packets to the indicated port at the indicated host at a rate determined by the local JACK daemon\&. The recv mode reads incoming packets at the indi\- cated port and writes the incoming data to a set of JACK output ports at a rate that is determined by the local JACK daemon\&.

-This transport mechanism is unreliable\&. Both send and recv clients will report buffer overflow and underflow occurences, and recv clients will report dropped and out\-of\-order packets, and shutdown on channel mismatch packets\&. In practice this mechanism can be made highly reli\- able over local networks\&.
