+"Usage : " PACKAGE " [OPTIONS]... FILES...\n"
+" Where a FILE is an image file or a directory.\n"
+" Multiple files are supported.\n"
+" Urls are supported. They must begin with http:// or ftp:// and you must\n"
+" have wget installed to download the files for viewing.\n"
+" Options can also be specified in the in the feh configuration file. See\n"
+" man feh for more details\n"
+" -h, --help display this help and exit\n"
+" -v, --version output version information and exit\n"
+" -V, --verbose output useful information, progress bars, etc\n"
+" -q, --quiet Don't report non-fatal errors for failed loads\n"
+" Verbose and quiet modes are not mutually exclusive,\n"
+" the first controls informational messages, the\n"
+" second only errors.\n"
+" -T, --theme THEME Load options from config file with name THEME\n"
+" see man feh for more info.\n"
+" --rcfile FILE Use FILE to parse themes and options from,\n"
+" instead of the default ~/.fehrc, /etc/fehrc files.\n"
+" -r, --recursive Recursively expand any directories in FILE to\n"
+" the content of those directories. (Take it easy)\n"
+" -z, --randomize When viewing multiple files in a slideshow,\n"
+" randomise the file list before displaying\n"
+" --no-jump-on-resort Don't jump to the first image when the filelist\n"
+" is resorted.\n"
+" -g, --geometry STRING Limit (and don't change) the window size. Takes\n"
+" an X-style geometry string like 640x480.\n"
+" Note that larger images will be zoomed out to fit\n"
+" but you can see them at 1:1 by clicking the zoom\n"
+" button.\n"
+" -f, --filelist FILE This option is similar to the playlists used by\n"
+" music software. If FILE exists, it will be read\n"
+" for a list of files to load, in the order they\n"
+" appear. The format is a list of image filenames,\n"
+" absolute or relative to the current directory,\n"
+" one filename per line.\n"
+" If FILE doesn't exist, it will be created from the\n"
+" internal filelist at the end of a viewing session.\n"
+" This is best used to store the results of complex\n"
+" sorts (-Spixels for example) for later viewing.\n"
+" Any changes to the internal filelist (such as\n"
+" deleting a file or it being pruned for being\n"
+" unloadable) will be saved to FILE when feh exits.\n"
+" You can add files to filelists by specifying them\n"
+" on the commandline when also specifying the list.\n"
+" -p, --preload Preload images. This doesn't mean hold them in\n"
+" RAM, it means run through and eliminate unloadable\n"
+" images first. Otherwise they will be removed as you\n"
+" flick through.\n"
+" --scale-down Automatically scale down images too big for the\n"
+" screen. Currently only works with -P\n"
+" -F, --full-screen Make the window fullscreen\n"
+" -Z, --auto-zoom Zoom picture to screen size in fullscreen mode,\n"
+" is affected by the option --stretch\n"
+" --zoom PERCENT Zooms images by a PERCENT, when in full screen\n"
+" mode or when window geometry is fixed. If combined\n"
+" with --auto-zoom, zooming will be limited to the\n"
+" the size.\n"
+" -w, --multiwindow Disable slideshow mode. With this setting,\n"
+" instead of opening multiple files in slideshow\n"
+" mode, multiple windows will be opened.\n"
+" -x, --borderless Create borderless windows\n"
+" -d, --draw-filename Draw the filename at the top-left of the image.\n"
+" --title TITLE Use TITLE as the window title in slideshow mode.\n"
+" -D, --slideshow-delay NUM For slideshow mode, specifies time delay (seconds,\n"
+" can be a decimal) between automatically changing\n"
+" slides.\n"
+" --cycle-once exit feh after one loop through a slideshow\n"
+" -R, --reload NUM Use this option to tell feh to reload an image\n"
+" after NUM seconds. Useful for viewing webcams\n"
+" via http, or even on your local machine.\n"
+" -Q, --builtin Use builtin http grabber to grab remote files\n"
+" instead of wget.\n"
+" mechanism, useful if don't have wget.\n"
+" -k, --keep-http When viewing files using http, feh normally\n"
+" deletes the local copies after viewing, or,\n"
+" if caching, on exit. This option prevents this\n"
+" so that you get to keep the local copies.\n"
+" They will be in the current working directory\n"
+" with \"feh\" in the name.\n"
+" --caption-path PATH Path to directory containing image captions.\n"
+" This turns on caption viewing, and if captions\n"
+" are found in PATH, which is relative to the\n"
+" directory of each image, they are overlayed\n"
+" on the displayed image.\n"
+" e.g with caption path \"captions\", and viewing\n"
+" image images/foo.jpg, caption will be looked for\n"
+" as \"images/captions/foo.jpg.txt\"\n"
+" -j, --output-dir Output directory for saved files. Really only\n"
+" useful with the -k flag.\n"
+" -G, --wget-timestamp When viewing http images with reload set (eg\n"
+" webcams), try to only reload the image if the\n"
+" remote file has changed.\n"
+" -l, --list Don't display images. Analyse them and display an\n"
+" 'ls' style listing. Useful in scripts hunt out\n"
+" images of a certain size/resolution/type etc.\n"
+" -L, --customlist FORMAT Use FORMAT as the format specifier for list\n"
+" output. FORMAT is a printf-like string containing\n"
+" image info specifiers. See FORMAT SPECIFIERS.\n"
+" -U, --loadable Don't display images. Just print out their name\n"
+" if imlib2 can successfully load them.\n"
+" -u, --unloadable Don't display images. Just print out their name\n"
+" if imlib2 can NOT successfully load them.\n"
+" -S, --sort SORT_TYPE The file list may be sorted according to image\n"
+" parameters. Allowed sort types are: name,\n"
+" filename, width, height, pixels, size, format.\n"
+" For sort modes other than name or filename, a\n"
+" preload run will be necessary, causing a delay\n"
+" proportional to the number of images in the list\n"
+" -n, --reverse Reverse the sort order. Use this to invert the order\n"
+" of the filelist. Eg to sort in reverse width order,\n"
+" use -nSwidth\n"
+" -A, --action ACTION Specify a string as an action to perform on the\n"
+" image. In slideshow or multiwindow modes, the action\n"
+" in list mode, or loadable|unloadable modes, the\n"
+" action will be run for each file.\n"
+" The action will be executed by /bin/sh. Use\n"
+" format specifiers to refer to image info. See\n"
+" FORMAT SPECIFIERS for examples\n"
+" Eg. -A \"mv %%f ~/images/%%n\"\n"
+" In slideshow mode, the next image will be shown\n"
+" after running the command, in multiwindow mode,\n"
+" the window will be closed.\n"
+" --action1 ACTION These extra action options allow you to specify\n"
+" --action2 ACTION multiple additional actions which can be invoked\n"
+" ... using the appropriate number key 1-9\n"
+" --action9 ACTION\n"
+" -m, --montage Enable montage mode. Montage mode creates a new\n"
+" image consisting of a grid of thumbnails of the\n"
+" images specified using FILE... When montage mode\n"
+" is selected, certain other options become\n"
+" available. See MONTAGE MODE OPTIONS\n"
+" -c, --collage Same as montage mode, but the thumbnails are\n"
+" distributed randomly. You must specify width and\n"
+" height or supply a background image or both\n"
+" -i, --index Enable Index mode. Index mode is similar to\n"
+" montage mode, and accepts the same options. It\n"
+" creates an index print of thumbails, printing the\n"
+" images name beneath each thumbnail. Index mode\n"
+" enables certain other options, see INDEX MODE\n"
+" OPTIONS\n"
+" -t, --thumbnails As --index, but clicking an image will open it in\n"
+" a new viewing window\n"
+" --cache-thumbnails Enable thumbnail caching\n"
+" -I, --fullindex Same as index mode, but below each thumbnail you\n"
+" get image name, size and dimensions\n"
+" --bg-tile FILE\n"
+" --bg-center FILE\n"
+" --bg-scale FILE\n"
+" --bg-seamless FILE Set your desktop background to FILE. Feh can\n"
+" use enlightenment IPC if you are running it,\n"
+" or will fall back to X methods.\n"
+" Feh stores the commandline necessary to restore\n"
+" the background you chose in ~/.fehbg. So to have\n"
+" feh-set backgrounds restored when you restart X,\n"
+" add the line \"eval `cat $HOME/.fehbg`\" to your\n"
+" X startup script (e.g. ~/.xsession). Note that\n"
+" you only need to do this for non E window\n"
+" managers.\n"
+" --fontpath PATH Specify an extra directory to look in for fonts,\n"
+" can be used multiple times to add multiple paths.\n"
+" -M, --menu-font FONT Use FONT for the font in menus.\n"
+" --menu-style FILE Use FILE as the style descriptor for menu text.\n"
+" --menu-bg BG Use BG for the background image in menus.\n"
+" --menu-border INT Specify number of pixels that define the menu\n"
+" background's border. Borders are not stretched\n"
+" when images are scaled.\n"
+" -N, --no-menus Don't load or show any menus.\n"
+" -1, --next-button B Use button B to advance to the next image in any\n"
+" mode (defaults to 1, usually the left button).\n"
+" -2, --zoom-button B Use button B to zoom the current image in any\n"
+" mode (defaults to 2, usually the middle button).\n"
+" -4, --menu-button B Use CTRL+Button B to activate the menu in any\n"
+" mode. Set to 0 for any button. This option\n"
+" is disabled if the -N or --no-menus option is set\n"
+" (defaults to 3, usually the right button).\n"
+" -5, --menu-ctrl-mask Require CTRL+Button for menu activation in\n"
+" any mode (default=off).\n"
+" -6, --rotate-button B Use CTRL+Button B to rotate the current image in\n"
+" any mode (default=2).\n"
+" -7, --no-rotate-ctrl-mask Don't require CTRL+Button for rotation in\n"
+" any mode -- just use the button (default=off).\n"
+" -8, --blur-button B Use CTRL+Button B to blur the current image in\n"
+" any mode (default=1).\n"
+" -9, --no-blur-ctrl-mask Don't require CTRL+Button for blurring in\n"
+" any mode -- just use the button (default=off).\n"
+" --xinerama [0|1] Enable/disable Xinerama support. Has no effect\n"
+" unless you have an Xinerama compiled in.\n"
+" --screen-clip [0|1] Enable/disable window clipping based on screen\n"
+" size. WARNING: with this option disabled,\n"
+" image windows could become very large, making\n"
+" them unmanageable in certain window managers.\n"
+" --hide-pointer In full screen mode, hide the X mouse pointer.\n"
+" FORMAT SPECIFIERS\n"
+" %%f image path/filename\n"
+" %%n image name\n"
+" %%s image size (bytes)\n"
+" %%p image pixel size\n"
+" %%w image width\n"
+" %%h image height\n"
+" %%t image format\n"
+" %%P prints feh\n"
+" %%v prints the version\n"
+" %%m prints the mode (slideshow, multiwindow...)\n"
+" %%l prints the total number of files in the filelist\n"
+" %%u prints the current file number\n"
+" \\n prints a newline\n"
+" Eg. feh -A \"mv %%f ~/images/%%n\" *\n"
+" MONTAGE MODE OPTIONS\n"
+" -X, --ignore-aspect By default, the montage thumbnails will retain\n"
+" their aspect ratios, while fitting in --thumb-width\n"
+" and --thumb-height. This option will force them to\n"
+" be the size set by --thumb-width and --thumb-height\n"
+" This will prevent any whitespace in the final\n"
+" montage\n"
+" -s, --stretch Normally, if an image is smaller than the specified\n"
+" thumbnail size, it will not be enlarged. If this\n"
+" option is set, the image will be scaled up to fit\n"
+" the thumbnail size. (Aspect ratio will be maintained\n"
+" unless --ignore-aspect is specified)\n"
+" -y, --thumb-width NUM Set thumbnail width in pixels\n"
+" -E, --thumb-height NUM Set thumbnail height in pixels\n"
+" Thumbnails default to 20x20 pixels\n"
+" -W, --limit-width NUM Limit the width of the montage in pixels\n"
+" -H, --limit-height NUM Limit the height of the montage in pixels\n"
+" These options can be used together (to define the\n"
+" image size exactly), or separately. If only one is\n"
+" specified, theother is calculated from the number\n"
+" of files specified and the size of the thumbnails.\n"
+" The default is to limit width to 800 pixels and\n"
+" calculate the height\n"
+" -b, --bg FILE|trans Use FILE as a background for your montage. With\n"
+" this option specified, the size of the montage will\n"
+" default to the size of FILE if no size restrictions\n"
+" are specified. Alternatively, if FILE is \"trans\",\n"
+" make the background transparent.\n"
+" -a, --alpha NUM When drawing thumbnails onto the background, apply\n"
+" them with a transparency level of NUM (0-255).\n"
+" -o FILE Save the created montage to FILE\n"
+" -O FILE Just save the created montage to FILE\n"
+" WITHOUT displaying it (use in scripts)\n"
+" INDEX MODE OPTIONS\n"
+" -e FONT Use FONT to print the information under each\n"
+" thumbnail. FONT should be defined in the form\n"
+" fontname/size(points). eg -e myfont/12\n"
+" -t, --title-font FONT Use FONT to print a title on the index, if no\n"
+" font is specified, a title will not be printed\n"
+" SLIDESHOW KEYS\n"
+" The default mode for viewing mulitple images is Slideshow mode\n"
+" When viewing a slideshow, the following keys may be used:\n"
+" p, P, <BACKSPACE>, <LEFT> Goto previous slide\n"
+" n, N, <SPACE>, <RIGHT> Goto next slide\n"
+" r, R Reload image (good for webcams)\n"
+" v, V Toggle fullscreen\n"
+" m, M Show popup menu\n"
+" c, C Caption entry mode. If --caption-path has been\n"
+" specified, then this enables caption editing.\n"
+" The caption will turn yellow and be editable,\n"
+" hit enter to confirm and save the caption, or\n"
+" hit escape to cancel and revert the caption.\n"
+" w, W Size window to current image dimensions\n"
+" h, H Pause the slideshow (only useful when using\n"
+" s, S Save current image to unique filename\n"
+" f, F Save current filelist to unique filename\n"
+" timed reloading or image changes)\n"
+" <, > In place editing, rotate 90 degrees right/left\n"
+" <HOME> Goto first slide\n"
+" <END> Goto last slide\n"
+" <ESCAPE> Quit the slideshow\n"
+" +, = Increase reload delay\n"
+" -, _ Decrease reload delay\n"
+" <DELETE> Remove the currently viewed file from the filelist\n"
+" <CTRL+DELETE> Delete the currently viewed file and remove it\n"
+" from the filelist\n"

+"\n"
+" MOUSE ACTIONS\n"
+" When viewing an image, a click of mouse button 1 moves to the next image\n"
+" (slideshow mode only), a drag of mouse button 1 pans the image, if the\n"
+" viewable window is smaller than the image, button 2 zooms (click and drag\n"
+" left->right to zoom in, right->left to zoom out, click once to restore\n"
+" 1x zoom), and mouse button 3 pans.\n"
+" Ctrl+button 1 blurs or sharpens the image (drag left to blur and right to\n"
+" sharpen). Ctrl+button 2 rotates the image around the center point.\n"
+" Button 3 activates the context-sensitive menu. Buttons can be redefined\n"
+" with the -1 through -9 (or --*-button) cmdline flags. All you people\n"
