-\chapter{Introduction}
-
-Robert \name{Bringhurst} quotes Frederick \name{Goudy}’s famous
-dictum on the topic of letterspacing: \quote{A man who would
-letterspace lowercase would steal sheep.}\footnote{\ctay{bh},
-p.~31.}
-Likewise other judgements:
-\quote{Letter spacing is a form of markup particularly hard
-to handle, that only master typographers should get involved
-with.}\footnote{\ctay{lt}, p.~126.}
-And another:
-\quote{Letter spacing is disapproved of in the same way as of
-capitals \uprightomiss~.}\footnote{\ctay{roemer}, p.~10.}
-This module is partly a reaction on the excellent article the
-last quotation was taken from, and partly the endeavour of a
-convinced \CONTEXT\ user and letter spacer to replace a number of
-kludges already in use with something more consistent.
-To be sure, those warnings are grounded in facts and they should
-seriously be taken into account before one resorts to
-letterspacing.
-
-Before the advent of \LUATEX\ the implementation of proper letter
-spacing in *\TEX\ proved to be extremely difficult.
-For instance, the \from [soulpackage] package provides some means
-but at the same time severely limits the content passed to
-macros.
-Nevertheless there are magnificent examples of letterspacing done
-right, like the \from [leibnizausgabe] by the Leibniz-Archiv in
-Hanover that has been typeset with \smallcaps{EDMAC} and \PDFTEX.
-Nowadays the Lua node library removes the technical restrictions
-and thus leaves the task of correct letterspacing to the user.
-The \te{Letterspace} module for \CONTEXT\ was designed to collect
-everything necessary to achieve this and to make it accessible
-from one place.
-
-\chapter{Commands}
-
-Technically, the \te{Letterspace} module doesn’t do anything
-fancy; it just maps some existing \CONTEXT\ macros into a single
-setup and lets you define and configure your own derivatives of
-it.
-The module is supposed to be loaded the regular way: somewhere
-before \type{\starttext} should be the line
-\starttyping
-\usemodule [letterspace]
-\stoptyping
-\noindentation-- That’s all.
-
-\section{Default Letterspace Command}
-Initially one letterspace command is already defined and
-configured, as well as a letterspacing environment.
-They are now ready for use in running text.

-\section{Defining and Customizing Letterspace Commands}
-
-The \te{Letterspace} module allows the letterspacing to be
-adjusted via \te{three} parameters.
-The \type{factor} determines the value by which the
-\te{intra}word spacing (between letters) will be extended.
-\type{spaceskip} specifies a dimension for the \te{inter}word
-spacing and, if applicable, the surrounding spaces.
-\type{suppresskern} allows for disabling the letter kerning which
-can improve the spacing of capitals (see below,
-\at{p.}[suppresskern]).
-
-The following lines reconfigure the predefined
-\type{\letterspace} macro to behave in an extreme fashion.
-\starttyping
-\setupletterspace [
-  factor=2,       % default: 0.125
-  spaceskip=2em,  % default: 0.5em
-]
-
-\letterspace{vapula!}
-\stoptyping
-\showsetup{setupletterspace}
-
-The recommended alternative to constantly readjusting the base
-command is to define separate macros for different purposes.
-
-\starttyping
-\defineletterspace [LSbighead]

-\chapter{Applications}
-
-\section{Precautions}
-
-\te{Letterspacing} is a dynamic property of a string of text, as
-opposed to static font properties that are e.g. italics or slant.
-In principle, when applying a letterspacing to text, the current
-font is not merely pushed back in favor of another font.
-Instead, the way of typesetting the same font is modified by
-certain parameters; in the case of the \te{Letterspace} module
-these are the \te{kerning} and the \te{interword space}.
-Therefore it exclusively depends on the correct adjustment of said
-parameters whether the letterspacing will achieve its purpose or
-not.
-On the other hand, external factors like harmonizing different
-typefaces, the font’s design size \etc. are ruled out as possible
-influences, which can be a great advantage if for example a font
-happens to lack a matching italic face for emphasizing.
-
-Due to its flexibility and because it poses relatively small
-demands on the typesetting environment, thoughtless letterspacing
-may easily ruin a product.
-Moderate values don’t express how important a particular emphasis
-is to the author? Just \ugly{widen the spacing} and no reader
-will ever skip over your message \dots.
-Sure, everybody will get the cue, though the appearance of the
-highlighted text, the paragraph, and possibly the whole page will
-certainly be spoilt.
-Granted, from this perspective letterspacing might appear to be
-too dangerous a tool, only begging for misuse.
-But this judgement is premature as letterspacing has in fact a
-long tradition and was employed in many outstanding examples of
-typography.
-Apart from its seductive versatility there are no objections
-against letterspacing on a general level, as long as it is
-carefully utilized.
-
-Letterspacing has two prevailing uses: ({\it1}) for emphases and
-({\it2}) for spacing capital letters, which is especially
-valuable in display situations like for instance the front matter
-of books or section headings.
-Both come with a set of peculiarities that the typesetter must
-consider in order to figure out the appropriate values for the
-interword and letter spacings.
-
-\section{Emphasis}
-Documents that require many levels of different emphases are
-among the primary targets of letterspacing.
-For example, in linguistics an author might wish to distinguish
-({\it1}) names of cited authors, ({\it2}) ordinary text emphasis,
-({\it3}) inline quoted passages, and ({\it4}) word forms or
-etymological roots.
-To be sure, this can be accomplished with a mapping like
-  {\it1}: small capitals,
-  {\it2}: italics,
-  {\it3}: quotation marks, and
-  {\it4}: a slanted face.
-But \te{quotation marks} are hard to keep track of, if the enveloped
-text exceeds a certain length; also, they disencourage skimming
-because the reader always has to check whether the point that
-caught his eye might belong to a quotation instead of the main
-text.
-In various fonts -- mainly sans serif -- \te{slant} cannot easily
-be told apart from italics, thus defeating the very purpose of
-emphasis, in other fonts it might not be available at all.
-\te{Bold face} might seem to be an obvious alternative but even
-semi bold weights cause text to stand out from the surrounding
-paragraph, diverting the readers attention away from its normal
-trail along successive lines.
-Besides, the more a text is intermingled with different weights,
-the closer it resembles the look of a dictionary.\footnote{%
-  \ctay{lt}, p.~122 distinguish \te{active} from \te{integrated}
-  markup.
-  Semi bold and underling belong to the former, italics and slant
-  to the latter.
-  As the effect of letter spacing heavily depends on the
-  environment, it may count as active when used as the only means
-  of emphasis.
-  However, in a “colorful” product with many different layers of
-  emphasis it might not stick out as much among the others and
-  thus count as integrated (cf. p.~126).%
-}
-
-After these deliberations the validity of \te{letterspacing,}
-including lower case, as a means of emphasis is already half
-established.
-It beats slant with respect to availability and differentiating
-effect.
-It is preferable over quotation marks because the emphasized
-passage clearly differs from the main font style.
-Finally, it triumphs over weight switching as the result is very
-close to the mean overall distribution of ink within the text
-body.
-In the previous graduation of emphasis levels an alternative
-involving letter spacing could be as follows:
-  {\it1}: small caps,
-  {\it2}: letterspaced text font,
-  {\it3}: italics, and
-  {\it4}: letterspaced italics or slants.
-Here another convenient feature of letterspacing becomes
-apparent: as it is basically a different method of typesetting
-the same font it can theoretically be applied on any typeface and
-weight.
-It follows, that in the foregoing mapping, parts of longer
-(italic) quotations may be emphasized as well:
-  \quote{%
-    regum timendorum in proprios greges {\uprightslash}
-    reges in ipsos imperium est \te{Iouis} {\uprightslash}

-However, substituting rule {\it2} for {\it3}, the resulting
-mapping will be less satisfactory.
-As quotations are prone to extending over multiple lines, whereas
-normal emphasis rarely spans more than two words, spacing out
-the former might lead to the unbalanced appearance of paragraphs.
-So best avoid letterspacing in cases where the object possibly
-encompasses entire sentences.
-
-Caution is necessary concerning \te{punctuation} adjacient to the
-letterspaced passage.
-In contrast to italicized or bold emphasis where an immediately
-succeeding punctuation sign is best typeset in the surrounding
-main face (e.g. „et {\it tu}, Brute?“), letter spacing may
-require the sign to be typeset as part of the emphasis.
-The reason for this consists partly in the larger interword
-spacing that extends onto the surrounding spaces, and partly also
-on the letterspacing itself which would be disrupted by a
-tighter-spaced character.

-Another natural use of letter spacing is to space out capitals and
-small caps, whose legibility suffers with increasing markup
-length.
-The appearance of capitals can be influenced in various ways, as
-demonstrated in the illustration to the left.
-In the first row, no modification is applied and the capitals are
-placed with full kerning.
-Row number two has the kerning removed and thus the distance between
-letters increases.
-The final row, as the second, lacks kerning and adds
-20\,\letterpercent\ letter spacing.
-\stophangaround
-
-As is apparent from the example, the difference in spacing
-particularly influences the outcome.
-The {\WORD unmodified text} in the first row is packed too
-tightly, whereas disabling the kerning results in irregular
-widening of the {\subff{kerning}\WORD previously kerned} letters
-near the center.
-In the third row the sequence looks much better because of
-additional \mediumcaps{\WORD letterspacing.}
-With some fonts \smallcaps{\sc small capitals} profit from additional
-spacing as well, as employed in the section headings of this
-document.\reference[suppresskern]{}
-The \te{Letterspace} module provides a switch \type{suppresskern}
-that, if set to {\it yes}, will disable kerning during
-letterspacing.
-This option is meant for the special treatment of capitalization
-but depending on the font it might equally help when dealing with
-emphasis as well.
