Re: Conditional including library based on platform

I have no problem using whatever it needs to get it done, I'm still
learning this system out (I have a lot more experience with GNU's
utils) and just having a hard time in general with the documentation.

I think my problem is that I don't really understand how alias will
help me, I've read:
http://boost.sourceforge.net/boost-build2/doc/html
/bbv2/advanced/builtins/targets.html#bbv2.builtins.alias
But it's much more of a general overview.

Also from the first example you sent you specified the conditional on
toolset, but I don't think that's a good approach considering a
windows user might be using the toolset "gcc" instead of something
obvious like msvc.

Perhaps the problem could really be solved by reading documentation
but I'm having a hard time finding a good set of docs with tutorials
examples etc... for V2.

Any suggestions or pointers would be greatly appreciated.
