+environment for virtual machines.  The key feature of NQP is that it's designed
+to be a very small environment (as compared with, say, perl6 or Rakudo) and is
+focused on being a high-level way to create compilers and libraries for virtual
+machines like MoarVM, the JVM, and others.
+
+Unlike a full-fledged implementation of Perl 6, NQP strives to have as small a
+runtime footprint as it can, while still providing a Perl 6 object model and
+regular expression engine for the virtual machine.")
