vocafortune has the following options:

-l : specify the directory vocafortune should look for fortunes
-f : specify a file for vocafortune to read

Vocafortune does not technically need to be used just for vocaloid songs.
It works similar to a fortune program in that it reads a text file with a delimiter and then returns an entry from that text file.  Forune uses %, I use backtick (`) because many more vocaloid songs use % in the title than do backtick. Because there are *some* songs that do use the backtick, it's not a 100% perfect solution, but literally every character I could find to use as a delimeter is used in vocaloid song names
