%description
A framework to assist creation of marine ecosystem models, generating
either 'R' or 'C++' code which can then be optimised using the 'TMB'
package and standard 'R' tools. Principally designed to reproduce gadget2
models in 'TMB', but can be extended beyond gadget2's capabilities. Kasper
