+xwax is an open-source Digital Vinyl System (DVS) for Linux.
+It allows DJs and turntablists to playback digital audio
+files (MP3, Ogg Vorbis, FLAC, AAC and more), controlled using a
+normal pair of turntables via timecoded vinyls.
+
+It's designed for both beat mixing and scratch mixing. Needle drops,
+pitch changes, scratching, spinbacks and rewinds are all supported,
+and feel just like the audio is pressed onto the vinyl itself.
+
+The focus is on an accurate vinyl feel which is efficient, stable
+and fast.
+
+Optionally install `faad' (AAC) and/or `ffmpeg' in advance for various
+additional audio formats. With stock Slackware packages, it already
+supports MP3, OGG, FLAC, WAV, AIFC & PCM.
+`xwax-import` needs `ffmpeg' for other media than MP3 or CDAUDIO.
+
+Note:
+xwax does not work without realtime priorities and so uses POSIX
+filesystem capabilities to execute with elevated privileges
+(required for realtime audio processing). This may be considered
+a security/stability risk.
+Please read http://www.slackbuilds.org/caps/ for more information.
+
+Optional dependencies: faad, ffmpeg

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
