 "raspistill" Camera App (commit )
 
 Runs camera for specific time, and take JPG capture at end if requested
 
 usage: raspistill [options]
 
 Image parameter commands
 
 -q, --quality   : Set jpeg quality <0 to 100>
 -r, --raw       : Add raw bayer data to jpeg metadata
 -l, --latest    : Link latest complete image to filename <filename>
 -t, --timeout   : Time (in ms) before takes picture and shuts down (if not specified, set to 5s)
 -th, --thumb    : Set thumbnail parameters (x:y:quality) or none
 -d, --demo      : Run a demo mode (cycle through range of camera options, no capture)
 -e, --encoding  : Encoding to use for output file (jpg, bmp, gif, png)
 -x, --exif      : EXIF tag to apply to captures (format as 'key=value') or none
 -tl, --timelapse        : Timelapse mode. Takes a picture every <t>ms. %d == frame number (Try: -o img_%04d.jpg)
 -fp, --fullpreview      : Run the preview using the still capture resolution (may reduce preview fps)
 -k, --keypress  : Wait between captures for a ENTER, X then ENTER to exit
 -s, --signal    : Wait between captures for a SIGUSR1 or SIGUSR2 from another process
 -g, --gl        : Draw preview to texture instead of using video render component
 -gc, --glcapture        : Capture the GL frame-buffer instead of the camera image
 -bm, --burst    : Enable 'burst capture mode'
 -dt, --datetime : Replace output pattern (%d) with DateTime (MonthDayHourMinSec)
 -ts, --timestamp        : Replace output pattern (%d) with unix timestamp (seconds since 1970)
 -fs, --framestart       : Starting frame number in output pattern(%d)
 -rs, --restart  : JPEG Restart interval (default of 0 for none)
 
 GL parameter commands
 
 -gs, --glscene  : GL scene square,teapot,mirror,yuv,sobel,vcsm_square
 -gw, --glwin    : GL window settings <'x,y,w,h'>
 
 Common Settings commands
 
 -?, --help      : This help information
 -w, --width     : Set image width <size>
 -h, --height    : Set image height <size>
 -o, --output    : Output filename <filename> (to write to stdout, use '-o -'). If not specified, no file is saved
 -v, --verbose   : Output verbose information during run
 -cs, --camselect        : Select camera <number>. Default 0
 -md, --mode     : Force sensor mode. 0=auto. See docs for other modes available
 -gps, --gpsdexif        : Apply real-time GPS information to output (e.g. EXIF in JPG, annotation in video (requires libgps.so.22)
 
 Preview parameter commands
 
 -p, --preview   : Preview window settings <'x,y,w,h'>
 -f, --fullscreen        : Fullscreen preview mode
