[Scons-users] Minimum Version for Tools

[Keith Prussing]

I'm looking at updating a [Tool] I developed for working with Pandoc.
I originally developed it for SCons <4.0.  I noticed that
`SCons.Warnings.Warning` has changed to `SCons.Warnings.SConsWarning`
with version 4. I personally rarely care about old versions when I
could be using the latest and greatest.  However, I would prefer to be
nice to other potential users.

My question is: What minimum version of SCons is considered good
practice to support?  I can work out the details of determining the
SCons version, but it's rather verbose and ugly (IMHO).
