Distributable VST Support (most for packagers)
Ardour now uses the Vestige header file to allow compilation with VST
support on Linux. We believe, given the reverse engineering of the
Vestige header, that there is no more need to fetch the VST SDK from
Steinberg in order to build Ardour with VST support, and it is possible
to distribute all source code associated with VST support. This means
that distributions are free to compile and release packages of Ardour
with VST support. Linux Packagers: *please* do not call such packages
"Ardour". They should *always* be named in a way to make it clear that
they contain VST support - Ardour with VST support is not actually a
Linux program at all (its a small Windows executable that is linked
against some Linux libraries, run by a shell script that invokes Wine).
It is critical that users have the choice to install 1 or the other (or
both, if possible). To repeat, Ardour with VST support should not be
packaged as "Ardour". I suggest "ArdourVST" (or ardourvst, for the
case-insensitive). Please note: VST is a trademark of Steinberg Soft-
und Hardware GmbH.
