+ Options:
+  -t <time> - Set time (in minutes) between screenshots; the number of screenshots is calculated automatically.
+  -n <number> - Set a fixed number of screenshots to take.
+  -m - Manual mode. Use arrows to FF/rewind. Press [S] to make screenshots. Quit mplayer to continue.
+  -r <percent> - Change the size of the output image. Less than 40% is recommended.
+  -s - Seed mode. Gives extra video and audio information. Removes spaces from filenames.
+  -h - Display this help message\n
+
+If you don't like screenshots run the script again.
+This script depends on Mplayer and ImageMagic. Make sure you have them installed.\n
+Usage example:
+shot -n 25 -r 35% ~/films/film.avi\n"
