readonly HELP='
al-places-pipemenu an Openbox Pipe Menu for showing a directory tree
It should normally be called from an openbox menu.

Usage:
    al-places-pipemenu [options] [directory tree root]

Options:
    -h,--help           show this message
    --recent            incorporate a "recent files" submenu
    --open <filepath>   open a file with configured default application
                        (in this case the script will not output a menu)

    If a directory tree root is not specified, $HOME will be used.

Configuration:
    /usr/bin/al-places-pipemenu may be edited directly for system-wide changes,
    or copied to ~/bin and edited there for per-user changes.

Editable variables and functions, at the top of the file:
    recent_script       path to a script outputting an openbox pipemenu
    open_folder_cmd     command to open folders - any file manager
    default_open_cmd    default command to open files
    text_editor         command to open text files
    open_file()         open files, using commands above, or alternatives
    shown_dotfiles      list of dotfiles to display (they are hidden by default)

    By default, this script will display directories separately, before files.
    To change this behaviour, see NOTE1, NOTE2 and NOTE3 near end of file.
