  o  Context prefix without trailing period - see Chapter 10, Commands

* Packaging

  o  The source release file is now packaged pretty much as a
     normal GNU distribution.  The automake and autoconf tools
     are used to create the Makefile and configure script.
  o  A few man pages have been included.  HTML versions of the
     man pages are included in the distribution, but do not
     install.  These are available online as well.
  o  A preliminary version of a NodeBrain function library is
     built and installed in the lib directory.  For example,
     on Linux it is installed as /usr/local/lib/libnb.a.  The
     headers are not installed, so experimentation requires    
     use of the headers in the distribution directory.
  o  Two skill modules nb_mod_simple and nb_mod_tree are included
     and install in the pkglib directory.  For example, on Linux
     they are installed to /usr/local/lib/nb/.
  o  A sample directory is included in the distribution with
     rule and event files for experimenting with the sample
     skill modules.
