[Scons-users] Tool exists?

[Gary Oberbrunner]

Right now, this only works for some tools, and only by convention between
related tools.  One of my top priorities is to think about revamping how
tools are initialized, including a concept of tool chains
(connected/related tools), which should give a much more robust framework
to do what you're asking for.
