# HOW TO USE:
# 1.create a file with the name pdf2mp3 and copy the content of
#   the whole text in there
# 2.make the file an executable via:
#   >>> chmod +x pdf2mp3
# 3.copy file to /usr/bin to make usage of program possible from everywhere on your computer:
#   >>> sudo cp pdf2mp3 /usr/bin/
# 4.after that get help calling: 
#   pdf2mp3 -h
#  
# 5.EXAMPLE:
#   you want to convert yourfilename.pdf into a mp3 file, then just type:
#   pdf2mp3 -v en -f yourfilename.pdf -o yourfilename.mp3   (for the english voice 'en', 
#                                                            for german voice 'de', type:
