# If you have a multicore machine, the build may be faster if using parallel
# jobs. The build system automatically adds -jN to the "make" flags, where N

# If you have installed wireless-tools comment out this line:

#ac_add_options --enable-startup-notification

# Uncomment the following option if you have not installed PulseAudio
#ac_add_options --disable-pulseaudio
# and uncomment this if you installed alsa-lib instead of PulseAudio
#ac_add_options --enable-alsa


# If you want to compile the Mozilla Calendar, uncomment this line:
#ac_add_options --enable-calendar
