% Notes
% ~~~~~
%
% The tag enit@ is used through the style
%
% To do:
% ~~~~~~
% - ref*, for adding stuff in the same fashion as label*
% - option ams, to force upshape, but I have to investigate
% how to do it.
% - labelled descriptions (ie, label, title, body)
% - A true nextline (far from trivial and perhaps solved with
% labelled descriptions).
% - Improved \AddEnumerateCounter
% - Compatibility with interfaces and zref-enumitem
% - "Pausing" somehow inline boxed text.
% - \@enumctr <-> \@listctr?
% - Define keys with values
% - Revise @nobreak

% +=============================+
%
% (1) The package uses a token register very often. To be on the
% safe side, instead of \toks@, etc., a new one is declared.
% (2) \enit@inbox is the box storing the items in boxed inline
% lists.
% (3) \enit@outerparindent is used to save the outer parindent
% so that it can be used in the key parindent
% (4) \enit@type has three values: 0 = enum, 1 = item, 2 = desc.
% (5) \enit@calc stores which dimen is to be computed:
% 0=labelindent, 1=labelwidth, 2=labelsep, 3=leftmargin,
% 4=itemindent
% (6) \enit@resuming has four values: 0 = none, 1 = series,
% 2 = resume* series (computed in group enumitem-resume),
% 3 = resume* list (ie, with no value).

% | KEYS |
% +=============================+
%
% Including code executed by keys.
%
% There are 2 keyval groups: enumitem, and enumitem-delayed.
% The latter is used to make sure a prioritary key is the
% latest one; eg, ref, so that the ref format set by label
% is overriden. So, when this key is found in enumitem,
% nothing is done, except the key/value is moved to
% enumitem-delayed.
%
% A further group (enumitem-resume) catches resume* and
% series in optional arguments in lists.

% ==================
%
% the next definition is somewhat tricky because labels are boxed.

% of text, but when the box is placed without horizontal material,
% leading is killed. So, we need change somehow \box to \unhbox, but
% I don't want to modify \@item. The code below presumes \@item has
% not been changed and arguments gobble the part setting \@labels,
% which is replaced by a new one.
%
% The default value in description is itemindent=!, but some styles
% (those whose item text begin at a fixed place, ie, nextline,
% multiline and sameline) change it to labelwidth=!.
%
% We must be careful with the group and the whatsit added by color to
% boxes. Alignment is applied here and some adjustments in skips are
% necessary to get proper line breaks (including a \nobreak at the
% beginning of \enit@align, ie, after the first whatsit, see above).
% To "pass" the inner group added by color to the box, \enit@postlabel
% ckecks if the following is }. ie, \egroup -- if not, the box has
% not reached yet its end.
