+liquid-dsp is a free and open-source digital signal processing (DSP)
+library designed specifically for software-defined radios on embedded
+platforms. The aim is to provide a lightweight DSP library that does not
+rely on a myriad of external dependencies or proprietary and otherwise
+cumbersome frameworks. All signal processing elements are designed to be
+flexible, scalable, and dynamic, including filters, filter design,
+oscillators, modems, synchronizers, and complex mathematical operations.
+
+Note: your CPU must support SSE3 instructions, for a list please see
+
+  https://en.wikipedia.org/wiki/SSE3

+# 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.

+liquid-dsp: liquid-dsp (Software-Defined Radio Digital Signal Processing Library)
+liquid-dsp:
+liquid-dsp: liquid-dsp is the software portion of Software Defined Radio. By using
+liquid-dsp: hardware that converts RF spectrum into a digital stream we are able
+liquid-dsp: to build complex radios to do many types of functions in software
+liquid-dsp: instead of traditional hardwre.
+liquid-dsp:
+liquid-dsp: Paired with a supported hardware receiver, you can use liquid-dsp to
+liquid-dsp: explore the RF world around you. Discover Satellite transmissions,
+liquid-dsp: Amateur Radio, Rail, Areonautical, Shortwave, or any number of
+liquid-dsp: possible signals floating through the air.
