    --help      | -h
                            Display this help and exit.

COMMANDS:
    task [ID]
                            Open the neorg context associated with the current context and
                            the uuid of the task with id ID. Without ID, it'll open the
                            current context's norg file.
                            If no context is set, drops you to the selection prompt

    dmenu
                            Select a project in dmenu mode. This will give you all projects
                            and exectute the selected one as in 'neorg projects <selected>'

    workspace [WS]
                            The neorg workspace (WS) to open at startup, an empty value drops
                            you at a prompt to enter the workspace yourself.

    project [P]
                            Opens the webbrowser with either the context (P) or
                            the current active context as argument if no context is supplied

    list
                            Lists all available contexts

    add
                            Allows you to quickly add projects

    fstart ID
                            Starts the task (ID) but only after it stooped
                            the previous active task, if it existed.

    fstop
                            Stops the current active task
ARGUMENTS:
    ID | *([0-9]) := [[%ID_GENERATION_FUNCTION]]
                            The function displays all possible IDs of the eligable tasks.

    WS := %ALL_WORKSPACES
                            All possible workspaces

    P := %ALL_PROJECTS_PIPE
                            The possible project
