Macro paradise is a plugin to the 2.10.x series of Scala compilers,
It is designed to reliably work with production releases of scalac,
making latest macro developments available way before they end up in future versions Scala.
Documentation~/210x $ scalac -Xplugin:macro-paradise_*.jar -Xshow-phases
phase name id description
---------- -- -----------
parser 1 parse source into ASTs, perform simple desugaring

Consult https://github.com/scalamacros/sbt-example-paradise for an end-to-end example, but in a nutshell working with macro paradise is as easy as adding these two lines to your build (granted you’ve already set up SBT to use macros):
resolvers += Resolver.sonatypeRepo("snapshots")
addCompilerPlugin("org.scala-lang.plugins" % "macro-paradise" % "2.0.0-SNAPSHOT" cross CrossVersion.full)
