# Portability notes:
# To guarantee this script works on all platforms that support fluxbox
# please keep the following restrictions in mind:
#
# - don't use if ! command;, use command; if [ $? -ne 0 ];
# - don't use [ -e file ] use [ -r file ]
# - don't use $(), use ``
# - don't use ~, use ${HOME}
# - don't use id -u or $UID, use whoami
# - don't use echo -e
# - getopts won't work on all platforms, but the config-file can
#   compensate for that.
# - various software like grep/sed/perl may be not present or not
#   the version you have. for example grep '\W' only works on gnu-grep.
#   Keep this in mind, use bare basic defaults.
# - Do _NOT_ suggest to use #!/bin/bash. Not everybody uses bash.

Usage: $command [-u/-U [wallpapersetter]] [-fFcCtTaA] /path/to/wallpaper
       $command [-u/-U [wallpapersetter]] [-fFcCtTaA] -r/-R /path/to/directory
       $command [-b/-B fbsetrootoptions]
       $command [-lhip]
Use \`\`$command -h'' for a complete help message.

Options:

    -u  Use specified wallpapersetter, use no argument to forget.

    -f  Set fullscreen wallpaper (default).
    -c  Set centered wallpaper.
    -t  Set tiled wallpaper.
    -a  Set maximized wallpaper, preserving aspect.
        ( if your wallpapersetter doesn't support this
          we fall back to -f )

    -r  set random wallpaper from a directory

    -b  Forward the rest of the arguments to fbsetroot(1).
        This can be used to set solid, pattern, or gradient backgrounds.

    -F,-C,-T,-A,-U,-B,-R same as lower-case, but without remembering.

    -h  Display this help.

    -l  Set previous wallpaper.

    -i  Information about selected wallpaper command.
    -d  (deprecated, use -i) Debug info.
    -p  Tips.


Files:

    ~/.fluxbox/lastwallpaper     In this file the wallpaper you set
                                 will be stored, for the -l option:
Environment variables:
    wpsetters   Wallpapersetters to use.
                example:
                  wpsetters=feh fbsetbg wallpaper.jpg

    DISPLAY     The display you want to set the wallpaper on.
                example:
                  DISPLAY=:0.0 fbsetbg -l

EOF
}

display_tips() {
    cat << EOF
Common tips to use with $command:

1) To replace all occurrences of bsetbg with $command in a file use this
   command:

   perl -pi -e 's,([^f]|^)bsetbg,$command,' filename

2) If you want to set the wallpaper and you want $command to
   remember the previous wallpaper put this in your ~/.fluxbox/overlay

   background: none

3) Use $command -i to find out what wallpapersetter $command will be
   used and what $command thinks about it.
