-% \subsection{Floating schemes}
-%
-% A number of approaches can be taken to redefining all float
-% types in a consistent manner (I know, I've tried several!).
-% In the end, the easiest method seems to be to use an ``internal''
-% float type in the package, and then define a related environment to
-% present to the user.  As a result, this part of the package is by
-% far the most complex.
-%
-% \DescribeEnv{scheme}
-% The |float| package allows new float types to be defined.  This is
-% used to create a |scheme| environment, which works very much like the
-% |figure| environment.    In contrast to the LaTeX default, all
-% float types are defined to be ``here'' if possible by default,
-% then float to the top of the page.  This is usually what chemists
-% expect to happen. All the float types are also defined to take one
-% optional argument to over-ride the provided placement behaviour.
-% The most likely use is to put |[H]| to force a float to be ``here'',
-% absolutely.  So for example, we might have:
-% \begin{verbatim}
-% Some text about \ref{sch1}, which will appear directly under this
-% paragraph and will not float at all!
-% \begin{scheme}[H]
-%   This is where the scheme should go%
-%   \caption{An exciting reaction, placed HERE.}%
-%   \label{sch1}
-% \end{scheme}
-% \end{verbatim}
-% To give:
-% \begin{quotation}
-% \noindent Some text about \ref{sch1}, which will appear directly
-% under this paragraph and will not float at all!
-% \begin{scheme}[H]
-%   This is where the scheme should go%
-%   \caption{An exciting reaction, placed HERE.}%
-%   \label{sch1}
-% \end{scheme}
-% \end{quotation}
-%
-% In addition to providing the floats, referencing to schemes, figures
-% and tables is formatted using the |varioref| package, to give
-% references such as ``Scheme 1'', ``Table 2'', \emph{etc.} from
-% simple \cmd{\ref} commands.
-%
-% \DescribeMacro{\listofschemes}
-% A listing command for schemes \cmd{\lisofschemes}, is provided in
-% analogy to \cmd{\listoffigures}.  It takes one optional argument to
-% alter the title of the list.  The \cmd{\listoffigures} and
-%\cmd{\listoftables} commands are redefined to act in the same way.
-%
-% A number of  package options are provided to alter the handling of
-% the floating environments.  By default, the float contents are
-% centred on the page. The option |floatleft| (also shortened to |fl|)
-% is available to produce the standard LaTeX behaviour of
-% left-aligned floats.  Captions are also centred by default, but may
-% be left-aligned using the |captionleft| (|cl|) option.  The format
-% of the labels once again follows the RSC or Wiley house styles.
-% Note that the |angew| package option automatically sets |cl| as
-% well. Finally, schemes may be numbered within chapters by using
-% the |chapter| (|ch|) option. This is obviously provided for
-% theses and other very long documents.
+% \subsection{Floats}
 %
-% \iffalse
-%<*template>
-% \fi
+% The float management section of |rsc| has been totally rewritten
+% in version 2.  The provision of a float type for schemes is now
+% handled by the |chemscheme| package; this is loaded automatically
+% by |rsc|.  The formatting of float types |table|, |figure| and
+% |scheme| is modified by the |rsc| package to conform to the
+% appropriate journal style.  This also applies to cross-references
+% and float captions.  The |rsc| package will pass any options
+% appropriate for |chemscheme| through to that package (currently,
+% these are |chapter|\footnote{Numbers schemes per chapter rather
+% than globally.} and |chemcompounds|\footnote{This option loads
+% the |chemcompounds| package, instead of the default of |bpchem|.
+% Both can be used to automatically track reference numbers given
+% to chemical compounds. See the |chemscheme| documentation for a
+% more detailed discussion of this option.}).
+%
+% \DescribeMacro{\floatcontentscentre}
+% \DescribeMacro{\floatcontentsleft}
+% By default, the contents of all floats are centred on the page.
+% This behaviour may be changed globally by using the |floatleft|
+% (or |fl|) package option.  The behaviour may be changed for
+% selected floats by issuing the command \cmd{\floatcontentscentre}
+% or \cmd{\floatcontentscentre} \emph{before} the beginning of the
+% floating environment.  This change remains in force until cancelled
+% using the complementary macro.
+%
+% Single line float captions are centred by default, but may
+% be left-aligned using the |captionleft| (|cl|) option.  The
+% |angew| option automatically activates |captionsleft|, as this
+% is the house style in Wiley journals.  All multi-line captions
+% are flush left.
+%
+% \subsection{Summary of options}
+%
+% The |rsc| package has a number of options, mainly concerned with
+% controlling formatting.  The full range of options is summarised
+% in \ref{option-summary}.

+% \section{Known issues}
+%
+% The |memoir| class implements its own customisable float and
+% caption management.  Unfortunately, this does not have flexibility
+% in the areas needed by the |rsc| package.  As a result, the
+% |memoir| methods are over-written with the procedures from the
+% |float| and |caption| packages.  This may cause some features to
+% fail or behave unexpectedly.  The decision to use |float| and
+% |caption| came down to considering the aims of \emph{this}
+% package.
+%
+% \section{Future plans}
+%
+% The |biblatex| package, currently being developed by
+% Phillip Lehman, is likely to become the standard for
+% bibliography formatting in the future.  However, currently
+% package is still in beta, and the interface is not finalised.
+% Thus at present it is too early to produce |biblatex| styles
+% for general release.
+%
+% Once |biblatex| reaches production, it is my intention to provide
+% suitable support files for chemical journals.  It seems likely that
+% these will be in a separate package (probably covering a number of
+% journal styles).  At that stage, the support macros provided here
+% may be moved to a more general purpose package.  It is my aim
+% to implement an extendable style system, to allow more convenient
+% support for a wider range of journals.  Suitable steps will be
+% taken to maintain the user interface provided here (and in the
+% |achemso| package).

+%
+% \subsection{Caption and float formatting}
+%
+% The |caption| package is used to control the appearance of
+% float captions. The macros provided by the |memoir| class do not
+% allow sufficient control, and so the functions provided by |memoir|
+% are ignored.  |caption| is loaded with the correct default format
+% for almost all floats.  In the case of \emph{Angew. Chem.}~style
+% formatting, tables are treated differently.
 %    \begin{macrocode}
 \ifRSC@angew
-  \floatstyle{plaintop}
-  \captionsetup[Table]{labelsep=colon}
-  \captionsetup[Scheme]{labelsep=period}
-  \captionsetup[Figure]{labelsep=period}
-\fi
-%    \end{macrocode}
-% The position of the caption on the line is set using the
-% |caption| package.  Slightly confusingly, a single line
-% caption can only be moved to the left-hand side using
-% the |singlelinecheck=off| command.
-% \changes{2007-01-01}{v1.1}{Switched to |cation| package
-% for centering labels}
-%    \begin{macrocode}

-  \captionsetup{singlelinecheck=off}
+  \RequirePackage[labelsep=quad,labelfont=bf]{caption}
 \fi
 %    \end{macrocode}
-%
-% The final task is to create a new float for chemical schemes.
-% In order to maintain consistency, we also redefine the table and
-% figure environments.  This is done by first creating ``internal''
-% float types, then formatting these.  The need for numbering
-% within chapters is also handled at this stage.
-% If there are no chapters the fall-back is simply to ignore the
-% request!
-% \changes{2007-01-01}{v1.1}{Altered error to package-specific}
+% By default, short (one line) captions are centred.  Longer captions
+% are typeset as paragraphs.  To set all captions flush left, the

+% captions.

 \fi
 %    \end{macrocode}
-% We now test if we want centered or left-aligned floating content.
-% This is achieved by using environments with the correct alignment

+%
+% The next step is to format the floats themselves correctly.
+% Unfortunately, |memoir| does not provide all of the commands
+% needed to achieve this.  Thus the |float| package is needed;
+% in order to load it, the \cmd{\newfloat} command in |memoir|
+% is killed off.  Notice that if |memoir| is not in use, the
+% |chemscheme| package will have already loaded |float|.
