+* NOTICE *
+* *
+* Unless you are developing the class libraries, you should *
+* not need to do any build steps in this directory. *
+* *
+* Go to ../mono and read the README file to compile and *
+* install. *

+*********************************************************************
+
+If you only want to build a snapshot or a fresh CVS checkout of the
+sources, you should go into the `mono' sibling directory and issue the
+make fullbuild command, like this:
+
+ cd ../mono
+ ./autogen.sh --prefix=/usr/local
+ make fullbuild
+
+That will build and install the code in a single pass. The
+compilation is bundled with the build due to dependencies on the class
+libraries on the runtime.
