This refactor IMO is a lot more readable than all the globals in the current code.

@ararslan perhaps this can be updated to just change `println` -> `info` since that is non controversial

You can use the `validate` function (not well documented......) > validate::Function You may pass a function to validate whether or not a certain library is usable, e.g. whether or not...

I'm wondering if there should be a method to do a force update, which would help in cases where the package does not have a validate function

Also seeing this here https://github.com/JuliaIO/ImageMagick.jl/issues/68 I tried tkelman's patch to no avail: ```julia ERROR: LoadError: Provider BinDeps.Binaries failed to satisfy dependency libwand Stacktrace: [1] satisfy!(::BinDeps.LibraryDependency, ::Array{DataType,1}) at C:\Users\Mus\.julia\v0.6\BinDeps\src\dependencies.jl:809 [2] satisfy!(::BinDeps.LibraryDependency)...

Good suggestion

@burdickjp Could you please try https://github.com/musm/WinRPM.jl ?

@robertdj that's because I removed the commits from my master branch and opened a PR with the changes. I can add them back to master branch if they help you.

@robertdj yes if you urgently need a fix please checkout https://github.com/JuliaPackaging/WinRPM.jl/pull/121 and let me know if it works?
