* User app installation *

ZeX/OS provides you many different apps you can use everyday.
There are favorite apps like irc client, netcat client,
email client, web client, web server, text editor,
music player, remote control server, some games,
calculator, grahical user interface, etc.

Just use script to install app from directory apps,
for example:
	./ iso app
Where 'app' specify name of app you want to install.


* User app running *

When you use howto * User app installation *, you should be able to
start apps from your CD-ROM directly.
First you have to mount your cdrom device to directory.
When you dont know, which device it actually is, use command: fdisk
There is list of connected ATA block devices like HDDs or CD-ROMs.
When it is cdrom device, you should see in list filesystem "isofs",
right after partition name, you want to mount (e.g. /dev/hdc0 : isofs).
Now you can use command like: mount /dev/hdc0 /mnt/cdrom
and when no error occured, just go to directory /mnt/cdrom by
command: cd /mnt/cdrom
Now you are able to start it by command: exec yourapp
