+% the \pack{curve2e} functionalities, and wrapping this
 % inserted text with the surrounding main text.
 %
 % The original software had some idiosyncrasies; Donald Arseneau
-% described them in the documentation of his package; I am sorry
-% to say that such idiosyncrasies have not been reduced; but in
-% any case in order to avoid such peculiar anomalies, it is

+% number of lines, i.e. by reasonably long paragraphs.
 %
 % The above implies that no wrapped object code should be specified
-% in the source file close the end of a paragraph; again no object
-% code should be inserted within any list; not even close to the end
-% or to the beginning of section. Arseneau's code is capable of
-% specifying the wrapping number of lines such that two or more
-% paragraphs can be indented so as to wrap a longish insertion,
-% but it is wise to avoid such risky situations. Moreover, if the

+% in the source file close the end of a paragraph, unless it is
+% followed by other paragraphs; again no object code should be inserted
+% within any list; not even close to the end or to the beginning of a
+% section. Arseneau's code is capable of specifying the wrapping
+% number of lines such that two or more paragraphs can be indented
+% so as to wrap a longish insertion, but it is wise to avoid such
+% risky situations. Moreover, if the inserted object has a numbered
+% caption, the number might not result in the correct sequence with
+% the normal corresponding floating objects.
 %
 % Therefore the usefulness of the wrapping procedure depends very
-% much from the document author ability to move around his/her code
+% much on the document authors' ability to move around their code
 % until a suitable position is found. Certainly a good place is
-% within a longish first section paragraph at the beginning of a
-% new chapter.
-%
-% The code of this package does not do anything to correct such
-% idiosyncrasies. They are caused by the limitations of the
-% \cs{ShipOut} native \TeX/\LaTeXe macro, and very little can be done in
-% addition to what Arseneau already did.
-%
-% Another purpose of this package is to add an option so that the
-% \meta{number of indented lines} argument does not mean the total
-% number, but the correction number to add-to or subtract-from to the
-% value computed by the default mechanism devised by Arseneau. We assume
-% that all user first use the software to insert an object to be wrapped
-% by the surrounding text without specifying any value with the
-% specific optional argument; then they evaluate the result, and if the
-% space below the wrapped object is too large, or if such space is
-% too small they count the necessary number of lines and specify
-% it to be processed during another document compilation. When the
-% object to be wrapped is tall, it is very easy to miscount the
-% necessary number of lines, while is is very easy to evaluate the
-% necessary small correction to the default computed value.
-%
-% A furher purpose of this package is to define a new environment,
-% \Env{wraptext}, to wrap a framed text block typeset on a grey
-% background as if it were a figure. On \texttt{texstackexchange}
-% a solution was suggested to a user who was asking for such an
-% arrangement; the solution resorted to a specific use of the
-% \Env{wrapfigure} environment. We thought that an \emph{ad hoc}
-% solution would be a better one, since the parameters to be used for a
-% figure have nothing or little to do with a text, therefore most
-% of them would be useless with a wrapped text. Nevertheless the
-% \meta{location} of the wrapped text and the optional correction
-% of the indented lines number would still be necessary. We added also
-% the possibility of optionally specifying the measure of the
-% wrapped text, even if this measure should not be too different
-% from a half of the wrapping text measure.In facts, with a value too

+% The code of this package does very little if anything to correct

+% necessary small correction to the computed value.

+% A further purpose of this package is to define a new environment,

+% background. On \texttt{texstackexchange} a solution was suggested
+% to a user who was asking for such an arrangement; the solution

+% specifying the measure of the wrapped text, even if this measure
+% should not be too different from a half the wrapping text measure.

+% either the wrapped text has problems with inter word spaces and
+% hyphenation because of the small measure, or, on the opposite, the
+% indented lines of the wrapping text would have similar problems. 
+%
+% Notice that the first implementation of this package, version~4.0,
+% achieved the desired result but there were two drawbacks: $(a)$
+% the syntax was different from that of the other environments,
+% and $(b)$ any possible caption was typeset within the same
+% framing environment. In version~5.0 both drawbacks were
+% eliminated, but since the environment syntax is different,
+% in oder to assure backwards compatibility a package option
+% was defined in order to fall back to the previous version~4.0
+% behaviour.

+% Please notice that both syntaxes, thanks to  differently

+% It may be useful to compare the \cs{includeframedtext} macro,

+% they refer to different objects to include. Their codes are
+% obviously very different and the latter is much more complex
+% than the former. The solution for a framed text used by
+% version~4.0 was inspired by the information found on

+% environment; version~5.0 uses instead a much simpler command
+% \cs{framedbox} based on the \pack{curve2e} package macro
+% \cs{Curve}. As it can be seen, the logic behind these different
+% macros are very similar.

-% be specified but it should not be too different from 50\% the

+% and its default value amounts to half the current measure; this

+% For the standard environments this parameter value appears to be
+% mandatory; actually it is a braced optional argument only for the
+% redefined environments \env{wrapfigure} and \env{wraptable}.
+%
+% Matter of facts, for the \Env{wraptext} environment we defined a
+% command in order to specify a factor $x$ so as to avoid getting the
+% object width outside the range  $xy_0 \leq y \leq y_0/x$, where $y_0$
+% is the preset default width; if the authors specified
+% a value outside this range, the above environment automatically
+% resets the insertion width $y$ to the nearest bound. Of course authors
+% have the possibility to change the preset $x$ value, if they redefine
+% the \cs{WFscalefactor} macro, but such resetting is strongly
+% discouraged; the default value is~$0.8$.
+%
+% If optional parameters are not used and the mandatory ones are
+% reduced to a minimum (remember the \meta{width}, in spite of being
+% braced is optional) the three environments produce the same results;
+% the difference, in spite of the nature of the wrapped object differs
+% only with the environment name. Text~\ref{fig:commodilla} displays

+% By reading the documentation of the original \pack{wrapfig} package,
+% it may be assumed that if the floating \meta{location} codes have to
+% be used, another floating object with the desired \meta{object name}
+% has to be previously  defined by means of the functionalities of other
+% packages or classes. But, if the non floating \meta{location} codes
+% are used, the presence of another \meta{floating object} environment
+% appears to be unnecessary.
+%
+% This is actually possible by “cheating” a little bit; it can be actually
+% wraped any \meta{object} by using the \Env{wrapfigure} environment,
+% while assigning a different name to the caption label; something
+% similar to typeset a small figure within a non floating environment.
+% The obvious draw back is that the caption is numbered as a figure.
+%
+% In order to avoid such drawbacks and to have a real floating
+% \Env{text} environment it is necessary to procede by defining
+% a new real floating environment with that name. To do this task,
+% \pack{wrapfig2} version~5.0 uses the \pack{float} package.
+%
+% As it is possible to verify by reading the section where the
+% code is documented, the operation is not that simple because
+% \pack{float} redefines several internal macros that are incompatible
+% with both \pack{wrapfig} and \pack{wrapfig2}. This is why, even 
+% with \pack{wrapfig2} in version~5.0, that loads the \pack{float}
+% package, the code for this environment  redefines the \cs{caption}
+% command so that Arseneau had to define some adjusting macros in order
+% to deal with something different from what it was with the \LaTeXe
+% kernel. We did not modify what Arseneau defined in although it did not
+% work correctly with the new \Env{text} floating environment. Therefore
+% we reinstated the \LaTeXe kernel relevant definitions.
+%
+% It is possible that such resetting of the original definition is
+% necessary also with floating objects defined by other means, for
+% example by using the functionalities of \class{memoir}. We admit
+% we did not test this package functionality with class
+% \class{memoir}; feedback on this compatibility issue is very
+% welcome

 %
 % Here we describe and comment the code of this package; essentially 
 % only the initial parts need some comments; because the final ones
-% are almost identical to the original Arseneau's code.
-%
-% We start with the usual specification of the format name and date,
-% and the identification of this specific package. We possibly load
-% the \pack{etoolbox} package, because we immediately need a
-% test on the existence of an @-protected macro; should this macro
-% already been defined by the class or other packages (including a

-% the loading is immediately aborted. If is was not previously loaded,

+%
+% The usual specification of the format name and date, and the
+% identification of this specific package have been already specified
+% by the \texttt{.dtx} file.
+%
+% First of all we check if certain packages have already been
+% loaded; some of these packages, such as \pack{wrapfig}, that
+% might have been previously directly loaded, or might have been
+% loaded by other packages, are incompatible with this new version 
+% (and also with the previous versions, but the problem was less
+% serious). That package might have been loaded by other packages,
+% such as \pack{caption} or \pack{subcaption}, that redefine some
+% internals that we did not want to replace so as to avoid other
+% possible incompatibilities. We first check if a specific macro
+% with the \texttt{WF} prefix has already been defined; if so,
+% this package loading is aborted with a very evident error
+% message. In contrast the job is not aborted, because the presence
+% of the original \pack{wrapfig} package might still be sufficient;
+% evidently there will be many errors if some new user commands
+% or environments are used.
+%
+%{\color{red}\paragraph{Caution} besides the evident error message,
+% that might be neglected by the user, the job may continue but it
+% may produce several errors difficult to interpret. Please,

+% In order to include the text to be wrapped the floating object

+% Here is the code of some extra macros and of the \Env{wraptext}

+%
+% Its simple syntax is the following
+%\begin{ttsintassi}
+%\cs{includeframedtext}\oarg{text width}\marg{text}\oarg{settings}\oarg{radius}
+%\end{ttsintassi}
+% 
+% The optional \meta{text width} is the (possibly scaled) width computed
+% by the \Env{wraptext} environment; but if the authors use this command
+% outside the \Env{wraptext} environment, they should specify a width;
+% in any case the default value is half the current measure
+% \cs{linewidth}. The \meta{text} is the unformatted text to be wrapped;
+% it will be boxed and framed by the service macro \cs{framedbox}; the
+% \meta{settings} are passed on to \cs{framedbox} command; they are a
+% comma separated list of dimensions, namely the thickness of the frame
+% and the necessary distance of the frame from the formatted text; the
+% last optional \meta{radius} is the curvature radius of the rounded frame
+% corners; no default value is specified, because it is going to be
+% received by \cs{framedbox} that by default sets it equal to the frame
+% separation width; this value is certainly the best one, but the user
+% can specify a different value, of course not too different from the
+% default one. See some examples in figure~\ref{fig:framed text}.
+%
+% The definition of the \cs{framedbox} command appears to be
+% complicated; it is just an apparent complication due to the
+% fact that it uses the powerful \cs{Curve} command that draws an
+% arbitrary curved line or fills the area delimited by the
+% curved line; it suffices to specify the nodes and the tangents
+% to each node; the nodes are the points the line should pass
+% through, their tangents may be specified with arbitrary vector
+% components along the horizontal and vertical axes. For a
+% rectangle such vector componente are just 0 or $\pm 1$. The
+% node coordinates, on the opposite, must be determined with
+% accuracy; we used the \cs{fpeval} function of package \pack{xfp},
+% that performs precise operation on operands in fractional
+% decimal numbers; if the operands are dimensions, the operands
+% are their fractional values in printer points, the results of
+% such operations are  pure fractional decimal numbers without units;
+% if the numerical result is to be interpreted again as the measure of a
+% dimensional entity, \texttt{pt} must be appended to the
+% assignments to a dimension register; within the \Env{picture}
+% environment, any coordinate is expressed in multiples of 
+% \cs{unitlength}.
+%
+% For a rectangle with curved corners of a given radius \cs{R}
+% we have four quarter circles joined by straight lines; therefore
+% we need eight nodes.
+%
+% The shaded background and the coloured frame have the same contour;
+% but the former is filled, while the latter is stroked; we have to
+% draw the same curve two times; first the shaded background, then
+% the frame.
+%
+% This shaded framed rectangle is at the center of the coordinate
+% system of a \Env{piture} environment, and has the correct dimensions
+% to receive the boxed text; it is trivial to center the text within a 
+% zero dimensioned box, typical of the \Env{picture} environment.
