using sdlang in sdp

https://github.com/Abscissa/SDLang-D/blob/master/HOWTO.md

**** build/ compile

The recommended way to use SDLang-D is via DUB. Just add a dependency to
sdlang-d in your project's dub.json or dub.sdl file as shown here. Then simply
build your project with DUB as usual. dub dependency
http://code.dlang.org/packages/sdlang-d


Alternatively, you can git clone both SDLang-D and the latest version of
libInputVisitor,

#+BEGIN_SRC d :tangle no
git clone https://github.com/Abscissa/SDLang-D
git clone https://github.com/abscissa/libInputVisitor
#+END_SRC

 and when running the compiler include:

#+BEGIN_SRC d :tangle no
 -I{path to SDLang-D}/src -I{path to libInputVisitor}/src
#+END_SRC

**** Importing

To use SDL, first import the module sdlang:

#+BEGIN_SRC d :tangle no
import sdlang;
#+END_SRC

If you're not using DUB, then you must also include the path the SDLang-D sources when you compile:

#+BEGIN_SRC d :tangle no
rdmd --build-only -I{path to sdlang}/src -I{path to libInputVisitor}/src {other flags} yourProgram.d
#+END_SRC

** read markup files
**** regular .sst
relatively straight forward
**** master .ssm
master files have been able to read in inser files .ssi and regular files .sst
***** reading in .ssi files is straightforward
***** reading in .sst files is more problematic
.sst files have their own root (structure)
either
- the root needs to be disabled - not used
or
- the root tree needs to be demoted, which is only possible if markup from
  heading D is not reached then A - C could be demoted to B - D
- the other issue there is that it is common not to write out heading level A
  text but to rely on the metadata for title and author, the issue there is that
  at present the header for .sst files that are imported is just lopped off and
  thrown away. At least the title and author information for each imported .sst
  file would have to read and available for use in its header A that is demoted
  to B
