#==========================================================
#This script is meant to be run whenever you want to make a new
#version of Milkyway@home nbody_lite. This script optionally (re)builds
#the MilkyWay@home Nbody binaries, and then (re)packages the folder
#mwah_nbody_lite, which will contain the files that should
#be released.
#==========================================================

#==========================================================
#$rebuild will build the binaries. Only needs to be done if
#milkywayathome has not been built yet, or if files have been
#changed or moved around since building.

#$package will create the mwah_nbody_lite folder (ready for release)
#prepared with all the binaries, documentation, and scripts that
#are needed to run MilkyWay@home Nbody.
#==========================================================

rebuild=true
package=true

#should always end up in the parent folder of the milkywayathome_client folder
