How to install the Oberon system:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You have following options to install the Oberon system:

	(1)	Installation as Super-User: this allows you
		to specify an owner of the Oberon system. All
		installed files will then belong to the given
		owner and group.
	(2)	Installation as "normal" user: all installed
		files will then belong to you.

Both installation procedures are supported by the install script.
Using the install_oberon script you have control on each step and
you decide where to place the Oberon system in your file system.
Thus, there are no unchangeable pathnames in the software.

Several parts of the Oberon System have to be recompiled
to adapt the Oberon System to your operating system and your
chosen file locations. This is done by install_oberon and
its associated makefiles.

The script has been written for sh(1) and it doesn't assume that
you have installed any additional packages or utilities. The
only exception is the formatting of manual entries. For this to
work, you need either groff or nroff.

Hints to install:
~~~~~~~~~~~~~~~~~

You have to invoke install_oberon in the directory where the script is in.
Every question install asks is given with an explanation, a prompt
and a default value (included in [...]).

Example:

Where to install binary files? Possible would be /usr/bin or
a directory with local binaries like /usr/local/bin.
bin-directory [/usr/bin]

Beside answering the question you have following options:

	?		repeat question
	!		escape to shell
	!command	execute command
	.		quit install

The prompt is repeated (with the exception of ".").

The installation procedure consists of 7 parts:

   1:  preparation of oc and the library
   2:  oc (driver of the compiler like cc)
   3:  compiler and library (in ./lib directory)
   4:  mmo (Oberon makefile generator)
   5:  odb (Oberon debugger)
   6:  manuals (in ./doc/man directory)
   7:  formatting manuals

Every part can be installed separately. (1) should be done
first. After installation of (1), (2) and (3) you are able to compile
and execute Oberon programs.

Install begins by asking for the set of parts to be installed.
The set is given by an ascending list of part numbers on a single line.
Default is "1 2 3 4 5 6 7" -- installation of all parts.

If you decide to run install_oberon multiple times, you will
notice that install_oberon asks during its initialization whether
it is OK to consider the previous settings. This allows you to
avoid reanswering all questions you have typed in earlier runs.

Disk usage: (3) requires 2.5Mb and (6)/(7) 1Mb, all other parts are
negligible.

The Oberon System in the distributed form has only been tested
for SunOS 4.1.1. It should run on all SunOS 4.*. However, it will
not run on earlier releases, e.g. SunOS 3.5. The memory managment
needs mmap(2) which has been introduced by SunOS 4.0.
