Consider adding a chapter on SBT

[anzelpwj]

Hi all,

Greatly enjoyed the book, but there's one thing I felt was missing. As a Python programmer, I'm very familiar with using pip and pypi to find whatever packages I need to extend my code, and it's the Python ecosystem that makes the language as powerful as it is. My very rough understanding is that sbt provides some similar functionality (as well as other build-tool items) and is a bit more standard for Scala than Maven is, and I think the book would be stronger if people knew where to look for useful Scala libraries and knew how use a build tool to link them. Would you consider adding a chapter on how to use SBT? I feel like you could extend the lesson where you downloaded the Apache Commons Math JAR to writing a build.sbt that downloads the package as a part of building the Scala project.

Anyway, just my suggestion.

Best,
Paul
