    vimwiki-cli is a command-line interface to Vimwiki, a plugin for the Vim
    text editor.  It provides a front-end for interactive editor commands and
    can be used to automate repetitive tasks such as rebuilding tag metadata
    and generating links, all from the command line.

    Global options may also be configured using environment variables:

    \b
    VIMWIKI_EDITOR        See --editor.
    VIMWIKI_COUNT         See --count.
    VIMWIKI_SELECT        See --select.
    VIMWIKI_OPEN_MATCHES  See --open-matches.
    VIMWIKI_OPEN_TABS     See --open-tabs.

    If no command is specified, the wiki index will be opened by default.
