    Python 2.6.
  * modinfo.sh contains build information now.

New in 0.7:

* Problems in cross-compiling PUPA are fixed.

* Use -mrtd and -mregparm=3 to reduce the generated code sizes.	This
  means that any missing prototypes could be fatal. Also, you must take
  care when writing assembly code. See the comments at the beginning of
  startup.S, for more details.

* New utility, ``pupa-setup''. This sets up PUPA to make it bootable
  from a real disk.

* New commands, "prefix", "insmod", "rmmod" and "lsmod" are added into
  the rescue mode to manipulate PUPA modules.

* Reduce the size of a core image significantly by compressing a large
  part of the core image and decompressing itself at boot time. The
  currently used algorithm is LZO (more precisely, LZO1X-999). So you
  have to install LZO to build PUPA. See
  <http://www.oberhumer.com/opensource/lzo/>, for more information.
