% I copied the magic from "memoir", a document class
% for typesetting poetry, fiction, non-fiction,
% and mathematical works.
% According to the basic user manual of "memoir",
% TeX tries very hard to keep text lines justified
% while keeping the interword spacing as constant as possible,
% but sometimes fails and complains about an overfull hbox.
% The default mode for LaTeX typesetting is \fussy
% where the (variation of) interword
% spacing in justified text is kept to a minimum.
% Following the \sloppy declaration
% there may be a much looser setting of justified text.
% Additionally the class ("memoir")
% provides the \midsloppy declaration
% which allows a setting somewhere between \fussy and \sloppy.
% Using \midsloppy one will get
% fewer overfull lines compared with \fussy
% and fewer obvious large interword spaces than with \sloppy.
