0.9.9 (pending)
++ Fixed a little endian problem in mton (Bastian Blank <waldi@debian.org>)
++ Fixed a arpping alignment problem (Rui He <rhe@3eti.com>)
+ Added sanity check for max_leases (udhcp bug #1285) (me)
+ Finally got rid of the trailing space in enviromental vars (me)
+ added an new enviromental variable: $mask. It contains the number
