altpdftex, altpdflatex, altpdfetex, altpdfelatex

iTeXMac only knows how to render pdf files, so it cannot display dvi nor ps file without a pre treatment. Also, certain situations don't allow the direct use of pdftex or pdflatex (when including complex ps files for example) and one has to use the old time sequence [tex|etex|latex|elatex]+dvips+ps2pdf.

In that situations, iTeXMac uses altpdftex, altpdflatex, altpdfetex and altpdfelatex which are shell scripts written by Gerben Wierda. Their purpose is to provide a unique command to translate tex, latex sources, dvi files into pdf ones.

iTeXMac includes those scripts in its generic projects with the same names. If you do not use Gerben Wierda teTeX distribution, you can remove those generic projects from your ~/Library/Application Support/iTeXMac subfolder

For those who do not use Gerben Wierda teTeX distribution, the script may be available from Gerben Wierda.
