[Boost-users] Boost sBUILD Features

Hi All, Does anybody have a link to a page that shows all the possible features (i.e. <threading>, <runtime-link>, etc.) for -sBUILD? I searched on google and the boost documentation but I can't find a good list of all the sBUILD features. I was just curious to see if I could use -sBUILD to control building 32-bit or 64-bit versions of the boost libraries. Thanks in advance, Rob
