These are the latest releases of the Unix ports of the ETH Aos system 
(Bluebottle, A2). The ports exist in three variants for Linux, Solaris
and MacOSX (Darwin).

New in this release:
   see Changelog.txt



Installation:
-------------

1. Unpack the System

      chmod +x install.UnixAos
      sudo ./install.UnixAos  {Solaris,Linux,Darwin}Aos.tgz


2. Create a directory in which you want to work with UnixAos (at 
   an arbitrary place _outside_ the Aos installation directory). 
   Change into that directory and start UnixAos

      mkdir workdir
      cd workdir
      aos

You are not limited to one working directory. If you want you can 
create a dedicated workdir for every project you are working on.

As the users get only read permissions for the Aos installation
directory the installed system can be shared by all users of the
host system.


Enjoy!

System Sources:
---------------

Starting with release 0.71 the system sources are kept in a subversion
repository at ETHZ. If you want to have a look at the sources and/or
make modifications to the system the following steps are sufficient:

First you need a local copy of the Aos svn repository:

   mkdir <somewhere>/aosrep
   cd <somewhere>/aosrep
   svn checkout https://svn.inf.ethz.ch/svn/lecturers/a2/trunk/source
   svn checkout https://svn.inf.ethz.ch/svn/lecturers/a2/trunk/UnixAos

Then create a working direcory with three links into the local copy of
the repository and a subdirectory NewAos and start Aos in the working
directory:

   mkdir <somewhere_else>/work
   cd <somewhere_else>/work
   ln -s <somewhere>/aosrep/source source
   ln -s <somewhere>/aosrep/UnixAos Unix
   ln -s Unix/buildtools Tools
   mkdir NewAos
   aos
