Introduction
------------
-grml2iso allows you to create a multiboot grml ISO. You can specify
-two or more grml ISOs and will get one single multiboot ISO as a result.
-grml2iso requires and uses grml2usb for this task and installs grub2
-as bootmanager on the multiboot ISO.

+You can specify two or more Grml ISOs and will get one single multiboot ISO as a result.
+grml2iso requires and uses grml2usb for this task.
+
+Important
+---------
+
+The order of the provided ISOs matters for two reasons:
+
+1) order in boot menu entries: the first ISO specified is listed as first (default) option in the boot menu, further ISOs will be listed below as next options
+
+2) EFI image to be used: the EFI image for booting via (U)EFI will be taken from the last provided ISO.
+Therefore to be able to boot on 64bit EFI systems, you need to provide a 64bit ISO (like grml64-small or grml64-full) as _last_ ISO in the grml2iso command line.
Options
-------
grml2iso supports the environment variables GRML2USB and WRKDIR.
GRML2USB specifies the path to the grml2usb script you'd like to use.
WRKDIR specifies the work directory for creating the filesystem.
-The work directory needs at least as much free disk space as the sum
-of all specified ISOs.

- *\-o <target.iso>*::
+ *-o <target.iso>*::
-This option is mandatory and specifies where the resulting multiboot grml ISO
-should be placed. Note that (to avoid any possible data loss) grml2iso will exit
-if the specified target.iso exists already.

+ *-r <boot param>*::
- *\-r <boot param>*::
+Remove specified boot parameter from existing command line.
+Can be specified multiple times.
-Remove specified boot parameter from existing command line. Could be specified multiple times.
+ *-p <grml2usb param>*::
+Execute grml2usb with the specified parameters.
+For a list of valid parameters have a look at the grml2usb(8) manual page.
+ *-s <URI>*::
+Generate a small ISO file which downloads the squashfs file from the specified URI.
+Due to current limitations in busyboxs wget and DNS resolution, an URL can not contain a hostname but an IP only.
+This is useful if you want to boot systems which support booting ISO image from your local system.
+Besides the ISO image this command also copies the squashfs file to the output directory.
