file's sole purpose was to provide a dependency on pkg-config and set
some environment variables. Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.
For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.
Dirac is a prototype video codec, under development by BBC R&D, and initially
released in March 2003.
Dirac is a general-purpose video codec aimed at resolutions from QCIF
(180x144) to HDTV (1920x1080) progressive or interlaced. It uses wavelets,
motion compensation and arithmetic coding and aims to be competitive with
other state of the art codecs.
