This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

This is PUPA, the Preliminary Universal Programming Architecture for
GRUB.  PUPA is a research project for the next generation of GNU GRUB.
The most important goal is to make GNU GRUB cleaner, safer, more robust,
more powerful, and more portable.

See the file NEWS for a description of recent changes to PUPA.

See the file INSTALL for instructions on how to build and install the
PUPA data and program files.

Please visit the official web page of PUPA, for more information.
The URL is <http://www.nongnu.org/pupa/>.



Because PUPA is still in developmental stage, PUPA is not for general
use (yet). For now, you can install PUPA into a floppy by these
instructions:

$ configure && make
$ ./pupa-mkimage -v -d . -o core.img chain fat
$ dd if=boot.img of=/dev/fd0 bs=512 count=1
$ dd if=core.img of=/dev/fd0 bs=512 seek=1

It would be easier to use Bochs <http://bochs.sf.net/> than a real
machine.
