-check (esp. Latex)  documenter.jl, 
-
-https://juliadocs.github.io/Documenter.jl/stable/man/syntax/#@example-block
-@example blocks support colored text output by mapping ANSI escape codes to HTML.
-   -- nothing for latex
-
-jupyter nbconvert, 
-        html: prima
-         latex mit juliamono: sind noch undef. escapesequencen drinne
-
-          \begin{tcolorbox}[breakable, size=fbox, boxrule=1pt, pad at break*=1mm,                 colback=cellbackground, colframe=cellborder]
-            \begin{Verbatim}[commandchars=\\{}]
-          sieht so aus, als wären da newlines reingekommen (vor der ascii-auswertung)
-    eliminate newline for esc??
