74 apulse (${apulse.meta.homepage}) implements most of libpulse
75 API over pure ALSA in 5% LOC of the original PulseAudio.
76
77 But apulse is made to be used as a wrapper that substitutes its
78 replacement libs into LD_LIBRARY_PATH. The problem with that is
79 that you still have to link against the original libpulse.
80
81 pressureaudio (http://git.r-36.net/pressureaudio/) wraps apulse
82 with everything you need to replace libpulse completely.
83
84 This derivation is a reimplementation of pressureaudio in pure
85 nix.
86
87 You can simply override libpulse with this and most
88 packages would just work.
