Tex programmer of course! I'm Java and C++ programmer, at the first look
Tex seems rather different than "normal or standard" languages!

Is a debugger a common tool in Tex/LaTex programming?

Lines are predetermined: the works are part of a Tibetan Data Input project
(medical texts): already typed, corrected and proofread. I have to generate pdf
files of those works with the same pagination, but not necessary the same
page layout, so page and line breaks are predetermined.

I will not ask you to make it, I just need some guidances and mainly where to
start as I'm new in Tex/LaTex but experienced software engineer.
