+ <flag name="low-memory">Build using PyPy with the engine configured towards low memory footprint. \
+ This makes it possible to build PyPy using ~3.5G of RAM on amd64 and ~half of that on x86,
+ at the cost of lengthened build time. Please note that you will need an extra ~1G of extra RAM or \
+ swap since the translation memory (unused at the time) is not freed when the C compiler is spawned.</flag>
