+$PRGNAM: $PRGNAM («Scala school» book)
+$PRGNAM: 
+$PRGNAM: Scala school was started as a series of lectures at Twitter to prepare
+$PRGNAM: experienced engineers to be productive Scala programmers. Being a
+$PRGNAM: relatively new language, but also one that draws on many familiar
+$PRGNAM: concepts, we found this an effective way of getting new engineers up to
+$PRGNAM: speed quickly. This is the written material that accompanied those
+$PRGNAM: lectures. We have found that these are useful in their own right.
