"""

Will generate an EDL list based on a searchword. This EDL list can later be used with mplayer

Usage: python video.py SEARCHWORD PATH_TO_VIDEOFILE

Example:
python video.py SEARCHWORD PATH_TO_VIDEOFILE > shortcut.edl
mplayer -edl shortcut.edl PATH_TO_VIDEOFILE

(it only properly works if srt file is in the same path and has exactly the same filename with srt ending!
