Re: Commandline interface for 8.0

Mike,

Thanks for tackling this.  Some thoughts:


> --encode
> --output stdout [default], mail
> --format text [default], html

An alternative is:
-- format html|encode

where multiple values allowed.  So
    --format html                      produces html
    --format encode                    encodes text
    --format html --format encode      produces html, then encoded
    --format encode --format html      same as previous

Alternatively, it could be --format "html,encode" but I don't know
if that's as easily done in GetOpt.

Also, maybe use "base64" instead of "encode".

So there does not need to be a --format text, but text is produced if
no --format specified.

Zip could also be another option for the format (--format zip)
instead of its own option.


> --mailto [flips output mail]

 From an implementation point of view, a warning could be printed if
--mailto or --save (or --file) are specified, but the corresponding
--output is not set properly.  This is not possible today (pre-8.0).

> --save [flips output stdout]

Or maybe --file or --filename (I think that may be more common in
UNIX/Linux when a filename is called for).
