Modified Files:
PipeServer.cpp ScripterCallback.cpp
Added Files:
Makefile
Log Message:
Modifications to script plugin:
Include a basic makefile based on one of Leland's. To be able to build the
plugin you need to fill in the Audacity path.
Linux - now there are separate pipes for each direction, same as the Windows
one.
Incidentally the problem with the second read failing was due to the test
script.
Temporarily disabled support for getting responses back from Audacity, because
this isn't yet handled on the Audacity side.
