Apply more or less same modifications on TOP as for SI3 for compliance
Despite remaining issues with references, TOP manual can be build like NEMO & SI3 with ./build_manual.sh TOP
For the record, the building of the 3 manuals can be launched with ./manual_build.sh all

9TOP (Tracers in the Ocean Paradigm) handles oceanic passive tracers in NEMO. At present, this component provides the physical constraints and boundaries conditions for oceanic tracers transport and represents a generalized, hardwired interface toward biogeochemical models to enable a seamless coupling.
10
11It includes three independent components : 
12
13\begin{itemize}
14        \item a transport code TRP sharing the same advection/diffusion routines with the dynamics, with specific treatment of some features like the surface boundary
15conditions, or the positivity of passive tracers concentrations
16        \item sources and sinks - SMS - models that can be typically biogeochemical, biological or radioactive
17        \item an offline option which is a simplified OPA 9 model using fields of physics variables that are previously stored to disk
18\end{itemize}
19
20There is two ways of coupling TOP to the dynamics :
21
22\begin{itemize}
23        \item \textit{online coupling} : the evolution of passive tracers is computed along with the dynamics
24        \item \textit{offline coupling} : the fields of physics variables are read from files and interpolated at each model time step, with no constraints on the time sampling in the input files
25\end{itemize}
26
27TOP is designed to handle multiple oceanic tracers through a modular approach and it includes different sub-modules :
28
29\begin{itemize}
30        \item the ocean water age module (AGE) tracks down the time-dependent spread of surface waters into the ocean interior
31        \item inorganic carbon (e.g. CFCs, SF6) and radiocarbon (C14) passive tracers can be modeled to assess ocean absorption timescales of anthropogenic emissions and further address water masses ventilation
32        \item a built-in biogeochemical model (PISCES) to simulate lower trophic levels ecosystem dynamics in the global ocean
33        \item a prototype tracer module (MY\_TRC) to enable user-defined cases or the coupling with alternative biogeochemical models ( e.g. BFM, MEDUSA, ERSEM, BFM, ECO3M)
34\end{itemize}
