;; According to https://golang.org/doc/install/gccgo, gccgo-4.8.2 includes a
;; complete go-1.1.2 implementation, gccgo-4.9 includes a complete go-1.2
;; implementation, and gccgo-5 a complete implementation of go-1.4.  Ultimately
;; we hope to build go-1.5+ with a bootstrap process using gccgo-5.  As of
;; go-1.5, go cannot be bootstrapped without go-1.4, so we need to use go-1.4 or
;; gccgo-5.  Mips is not officially supported, but it should work if it is
;; bootstrapped.

      (description "Luar is designed to make using Lua from Go more
convenient.  Go structs, slices and maps can be automatically converted to Lua
tables and vice-versa.  The resulting conversion can either be a copy or a
proxy.  In the latter case, any change made to the result will reflect on the
source.

Any Go function can be made available to Lua scripts, without having to write
C-style wrappers.

Luar support cyclic structures (lists, etc.).

User-defined types can be made available to Lua as well: their exported
methods can be called and usual operations such as indexing or arithmetic can
be performed.")
