Description: Fix pdflatex invocation
 In /usr/share/texlive/texmf-dist/web2c/texmf.cnf, openout_any is set to p
 (paranoid), so that LaTeX does not allow to write out of the current
 directory and its sub-directories.
 .
 Override that in the pdflatex invocation to avoid error:
 Not writing to ../html/examples/group/latex//group__group2.aux
