# 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, use whoami
# - 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.
#   Non portable features like getopts in this script can be achieved in
#   other ways.

Options:

    -f  Set fullscreen wallpaper
    -c  Set centered wallpaper
    -t  Set tiled wallpaper
    -a  Set maximized wallpaper, preserving aspect.
        ( if your bgsetter doesn't support this
          fbsetbg falls back to -f )

    -F,-C,-T,-A same as uncapsed but without remembering.

    -h  Display this help

    -l  Set previous wallpaper

    -d  Debug fbsetbg
    -p  Tips

Files:

    ~/.fluxbox/lastwallpaper     In this file the wallpaper you set
                                 will be stored, for the -l option:

EOF
}

display_tips() {
    cat << EOF

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

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

2) If you want the style to set the wallpaper and you want fbsetbg to
   remember the previous wallpaper put this in your ~/.fluxbox/init

   session.screen0.rootCommand:    fbsetbg -l

3) Use fbsetbg -d to find out what wallpapersetter fbsetbg will use and
   what he thinks about it.
