# make install-package -- build and install package for current platform (sudo!)
# make purge     -- remove any installed package, INCLUDING data (sudo!)
#
# make dist      -- prepare dist/ tree for distribution
# make install   -- install amtc and amtc-web, respects $DESTDIR
# make deb       -- build debian/raspian package of amtc incl. amtc-web
# make rpm       -- build RPMs (RHEL/CentOS/Fedora...) of amtc and amtc-web
# make osxpkg    -- build OSX installer .pkg
