Convert a searchable pdf in djvu

Well, why would I wanto to do that? Because in general djvu’s take up less space. Anyway, if you have a Mac with macports, issue from the terminal

    sudo port install pdf2djvu

and then use it with

    pdf2djvu -o name_of_the_file.djvu  --monochrome name_of_the_file.pdf 

where I used

    --monochrome

because I just had a black and white pdf. For more options,

    man pdf2djvu
