+  A sequence container similar to the C++
+  [[http://www.cplusplus.com/reference/vector/vector/][std::vector]], but
+  instead of allocating memory dynamically, this container points to an
+  external, statically allocated c style array. The maximum size is
+  fixed at compile time, but the size can change by pushing and popping
+  elements from the vector. Static memory allocation is used to avoid
+  dynamic allocation problems on very small embedded processors. Care
+  must be taken not to dereference an empty vector, access elements
+  beyond bounds, or use without setting the storage array.
+
+  This library is very similar to
+  [[https://github.com/janelia-arduino/Array][Array]], however Array
+  stores data internally in the container and this library stores data
+  externally. The pointer to the external memory causes this container
+  to use more memory than the Array container, but storing the data
+  externally avoids needing the maximum size as a class template
+  parameter.
