see string substitutions in https://github.com/lamastex/scalable-data-science/blob/master/babel/texHunt.md

for example see:
https://github.com/lamastex/scalable-data-science/blob/master/db/2/2/017_LAlgIntro.scala
and its current malformed md that is hooked into gitbook:
https://github.com/lamastex/scalable-data-science/blob/master/gb/sds-2-2/017_LAlgIntro.md

after running:

It works fine at least with KaTeX through Pandoc (I can't really try with gitbook).

NOTE(!!!): I've added a new output format called markdown-katex, if you want the weird double dollar sign syntax for math (that gitbook with katex seems to be using) use "-t markdown-katex" instead of "-t markdown"
