Lately I've discovered that the
pdftex (with some other one) binaries in Ubuntu are the same:
lrwxrwxrwx 1 root root 6 лип 29 18:03 latex -> pdftex* lrwxrwxrwx 1 root root 6 лип 29 18:03 pdflatex -> pdftex* lrwxrwxrwx 1 root root 6 лип 17 20:22 pdfcslatex -> pdftex*
Executing all without any options yields different results; so, my assumption they use
What is the advantage of using
argv instead of compiling several binaries? And what other usages of
argv is possible?
