-:: The bootstrap flow has been removed. This file's only purpose is to make the
-:: transition smooth as the previous update script called bootstrap\gclient.bat
-:: The current flow took place on March 21, 2012. This file should be removed
-:: when it is believed everyone has updated since then.
-
-:: At this point we know %DEPOT_TOOLS_UPDATE% != 0 as in the previous script
-:: bootstrap\gclient.bat was only called if this was the case.
-
-:: Update the root directory. The previous version only supported svn so there
-:: is no need looking for git here (i.e. if someone has git they can't get to
-:: this point where the bootstrap dir is gone during the update anyways...)
