+  Yosys is a framework for Verilog RTL synthesis. It currently has
+extensive Verilog-2005 support and provides a basic set of synthesis
+algorithms for various application domains. 
+
+  Yosys can be adapted to perform any synthesis job by combining the
+existing passes (algorithms) using synthesis scripts and adding
+additional passes as needed by extending the yosys C++ code base.
+
+  Yosys is free software licensed under the ISC license (a GPL
+compatible license that is similar in terms to the MIT license or
+the 2-clause BSD license).
+
+
+  By default it compiles using gcc if you want to use clang set
+the environment variable CLANG=yes.
+  If you want to enable GHDL set GHDL=yes, this requires the GHDL
+package.
+  For enabling protobuf install protobuf3 and set PROTOBUF=yes.
+  For building the python wrappers set PYTHON=yes.
+  If you want to enable ABC for synthesis and verification of
+binary sequential logic circuits set ABCEXTERNAL=yes, this
+requires berkeley-abc package.

+# 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.
