+    (description
+     "Quirrel is a script language that is based on Squirrel language and is
+inspired by Python, Javascript and especially Lua, with
+
+    Lexical scoping
+    Higher order functions, closures and lambda
+    Classes and inheritance
+    Tail recursion
+    Delegation
+    String interpolation
+    Exception handling
+    Cooperative threads (coroutines)
+    Generators
+    Performance - Quirrel is fast and small (comparable with Lua and sometimes even faster)
+    Both compiler and virtual machine fit together in about 13k lines of C++ code and add only around 100kb-150kb the executable size.
+    Automatic memory management (CPU bursts free - reference counting and GC)
+    Optional 16bits characters strings
+    Dynamic typing type system is close to Javascript but stricter and simpler (there is integer type and no 'undefined')
+    Powerful embedding api
+    Modules
+    Hot-reload (if you implement it in your code)
+    Open Source MIT License")
