Usage: $__self [OPTIONS]

Installer for Maemo $__version $__release release.
Scratchbox installation is a precondition of running this script.

Creates '$__armel_target' and '$__i386_target' scratchbox targets, downloads
and installs the maemo $__version rootstraps and installs system files
to these targets.

If you choose not to accept the license or download the installer (e.g.
using the '-f' option), these components will not be installable and
they are not available anywhere else.

Options:
	-v	Display version and exit.
	-h	Show this usage guide.
	-y	Yes, force remove of existing targets.
	-d	Use defaults. Non-interactive mode.
	-p URI	Specify http_proxy for scratchbox user (default no proxy).
	-s PATH	Specify Scratchbox installation path (default /scratchbox).
	-q NAME	Specify Qemu version (default $__armel_cputransp).
	-a FILE	Specify alternative sources.list file for both targets.
	-A	Advanced mode
	-D	Set the DISPLAY to export (default :2, noop if already set)
	-n	Specify a prefix for the target names.
	-m PKG	Specify the installed module for non-interactive mode.
		(default options: none, maemo-sdk-runtime, maemo-sdk-dev,
		maemo-sdk-debug. Defaults to maemo-sdk-dev.)

IMPORTANT! Please read this. 

You now have the maemo $__version $__release installed on your computer.
You can now start your maemo SDK session with $__scratchbox/login and
then select your target with 'sb-conf select $__armel_target' for the
armel target or 'sb-conf select $__i386_target' for the i386 target.

If you have any problems with targets' package databases, you can try
running 'fakeroot apt-get -f install' on your scratchbox target.
This command will try to fix any problems with the package database.
