# Make a systemwide installation of dosemu.
#
# NOTEs:
#
#	1. 'make' and 'make dosbin' must have been done prior to this
#
#	2. You must have available dosemu-freedos-bin.tgz somewhere
#
#	3. This installs a non-suid-root DOSEMU, which is almost fullfeature
#	   when running under X. If you want graphics on the console
#	   or want to access hardware (such as ports and IRQ passing), you
#	   need a suid-root installation. However, because this is
#	   inherently insecure and dangerous (you may lock your machine)
#	   we won't support/recommend it for normal usage and expect only
#	   skilled people (and those respecting 'RTFM';-) being able to use
#	   it properly. Hence, no 'automagical' suid-root install any more.
#
#
# this script is obsolete, but just keep it as a "make install" front end
# for now

 ./install_systemwide [-fd FD_tarball] [-r root] [ -i instpath] [-b binpath]

 where is

  FD_tarball	Tarball containing FreeDos part of the DOSEMU binary
		distribution as available on the official DOSEMU site:
		       ftp://ftp.dosemu/org/dosemu/dosemu-freedos-bin.tgz
		(give the local filename where you downloaded it)
		If this argument is ommitted, the script assumes you have
		already put it to <instpath>/dosemu-freedos-bin.tgz, if it
		is not in place, the script aborts.

  root		optional prefix for 'instpath' and 'binpath', so you can make
		packages out of the installation without messing up your
		running system setup. 'root' will only be taken for copying,
		not for configuring and this tree is not useable until
		it gets moved to the proper instpath/binpath.

  instpath	Path in the (installed) system where the DOSEMU templates,
		binaries and docs will reside. Default is /opt/dosemu.

  binpath	Path where symlinks of the executables are placed.
		Default is /usr/bin.
