\ProvidesClass{recipe}[1996/11/22 MLO recipe class v0.9]
%
% Recipe class; intended to be used to produce a ``book''
% of recipes---so that loads book.cls . This file is in
% the public domain, and comments/additions/modifications
% are welcomed to be EMailed to me, i.e. to:

%
% The \part, \chapter, \section and \subsection commands
% work as usual; \subsubsection commands are used for
% ``recipes'' as units, and are not numbered but (by
% default) entered in the .toc file.
%
% The recipe (a.k.a. subsubsection header) is typeset in
% a style defined with the command \rechead; the default
% is Large, horizontally centered, bold sans-serif: and
% the user can change that setting with a suitable
% \renewcommand{\rechead} .
%
% If e.g. \section and \subsection commands are not used
% in the text, the large indentation of the \subsubsection
% items in the Table of Contents may be ugly; in that case,
% you should redefine appropriately \l@subsubsection .
% The book.cls definition is:
% \newcommand*\l@subsubsection{\@dottedtocline{3}{7.0em}{4.1em}} ;
% the second parameter (7.0em) is the initial skip, and
% the third (4.1em) is the length for the subsubsection
% number field (if the subsubsections are to be numbered).
% As an example, a redefinition of \l@subsubsection may look
% like:
% \makeatletter
% \renewcommand*\l@subsubsection{\@dottedtocline{3}{3em}{4.1em}}
% \makeatother
%
% A specific command \recipe{...} is defined as an alias
% for a \subsubsection{...} followed by two rules across
% the whole page and by a vertical space.
%
% Another command, \ingred{...}, is defined to typeset a
% list of ingredients (the \ldots) with the italic font,
% inside a ``quote'' environment and after an ``ingredient
% header'' \inghead---empty by default, and that can be
% redefined by the user with, e.g., a
% \renewcommand{\inghead}{\textbf{Ingredients (4 persons)}:\ }
% (note the trailing space).
