# A simple build front end. Use this to run make -s and still get a list of all
# commands in buildlog.txt for inspection on errors. Just run it with the same
# arguments as make. Make will always be invoked from the Zomp root dir
#
# Also supports doing multiple make invocations.
# For example ./build.sh DEBUG=1 -k clean,all,test will invoke
# make DEBUG=1 -k clean; make DEBUG=1 -k all; make DEBUG=1 -k test
