Moved from MD to LaTeX for documentation. Content maybe shared between two or more documents. Was copying and pasting to fix multiple locations for simple spelling errors. Now there is a single LaTex file to edit for all complete documents. Issue is that the file system layout is more like this: /Product A/images/ /Product A/revision.tex /Product A/instalwin7.tex /Product A/instalwin10.tex /Product A/layout.tex /Product B/layout.tex /Commmon/images/ /Common/companyinfo.tex /Common/header.tex /Win7/images /Win7/access-cmd.tex /Win10/images /Win10/access-cmd.tex Where Product A and Product B layout.tex links all LaTex files needed to build a complete document.
