even if the news is still some days old - its worth mentioning:
batman-advanced is now available in Debian!
The packages are available through your favorite dpkg frontend (apt-get,
aptitude, ...) using the unstable repositories. To follow the package
development you can visit the following pages:
batman-adv-source contains the source code and can be compiled for your kernel
using module-assistant . batman-adv-battool contains the battool which
provides ping, traceroute and other tools for the batman-adv network.
Big thanks to Sven Eckelmann, Simon Wunderlich and Holger Levsen for their
work on these packages. :)
BTW, you also can find the current batman stable (0.3) in the lenny and
unstable repositories. Here the respective package pages:
