[Scons-dev] How to get variables passed to Env(variables = whatever)?

OK... well, my question was how to control it? Right now it does the
opposite of what I need. How to make it do what I need?
I.e. I want to allow FLEX_HOME to be set in this way (this is a
directory name, so the way variables have special function for
directories looks appealing)

No. This variable is most likely not set in the shell environment,
when the build script is called. It is very likely that users will
have to set it.

Fair enough... but I thought it's a suggested way of doing it.

Not sure. I want to pass it to my function, that will do something
based on that variable (in this particular case, it will try to find a
bunch of programs, configuration files etc.)

Best.
