--

|

-- definition table. If omitted the buttons are shown. When not shown the

--

-- Some formspec elements do not properly start at 0,0 even if set so. The
|

-- `content_offset` attribute offsets the content vertically by the given
|

-- amount of units. Formspec height and button positions are adapted to the
|
||
-- given value.
|
||
--
|
||
-- The table entries for `formspec` are the usual formspec elements that
|
||
-- define what a formspec looks like. You can write all definition in one entry
|
||
-- or split the definition into multiple entries.
|
||
--
|
||
-- The definition defines the CONTENT of the formspec not the whole formspec so
|
||
-- you can easily start at 0,0 for your definition. The function automatically
|
||
-- places everything in relation to the formspec frame and default buttons.
|
||
--
|
||
-- The minimum formspec width and height are 10 units in width and 5 units in
|

-- height. So `width` and `height` can be omitted when all of your content fits

-- into the default size.
|

|
||
-- start with a plus sign (+) and are read until any character that is not
