    INSTALLATION                                                     *installation*
    
    Drop it on your Pathogen path and you're all set.
    
    FEATURES                                                             *features*
    
    The syntax highlighting includes:
    
    * The directives (e.g. FROM)
    * Strings
    * Comments

    let b:current_syntax = s:current_syntax
    syntax region shLine matchgroup=dockerfileKeyword start=/v^s*(RUN|CMD|ENTRYPOINT)s/ end=/v$/ contains=@SH
    " since @SH will handle "" as part of the same line automatically, this "just works" for line continuation too, but with the caveat that it will highlight "RUN echo '" followed by a newline as if it were a block because the "'" is shell line continuation...  not sure how to fix that just yet (TODO)
