+
+IMPORTANT NOTE:
+
+These fonts make use of the 256-character capabilities of gf
+format. They cannot be converted to the obsolete PXL format which
+allows only 128 characters. If you are still using PXL format
+drivers, it is time to convert. If you are using a gf format
+driver with only 128 character capacity, you are missing
+something. See doc/install.tex.
+
+Metafont must have |max_in_open| increased (to 10) to compile
+these fonts as they stand. The appropriate change has been added
+to the change files on the UnixTeX distribution. If you're
+getting these fonts other than from the TeX distribution, and if
+you don't have access to Metafont source, you'll have to merge
+some files before you attempt compilation:
+
+ In src/s.mf, replace the line readfrom("gen_sigma") by the
+ contents of src/gen_sigma.mf.
+ In src/lower.mf, replace each line by the contents of the
+ corresponding file; for instance, replace readfrom("a") by
+ the contents of src/a.mf.
+ In greek.mf, right after the line that says ``font_setup''
+ insert the lines
+
+ readfrom("gen_acc");
+ readfrom("gen_sigma");
+
+HMC:
+At HMC a couple of modifications have been made to the MF files:
+
+ The definition of readfrom has been changed so that no
+ directory information is present.
+ accent.mf has been renamed graccent.mf and punct.mf has been
+ renamed grpunct.mf to prevent conflicts with CM files.
+
+ TODO:
+create digamma
+add kerning, especially between accents and capitals
+create more typefaces (italics?)
+complete hyphenation table
+create tick marks for numbers

+\heading A Bit of History \endheading
+
+During the first four centuries after the introduction of the printing
+press in Europe, the printing of Greek was hampered by the relative
+inadequacy of existing types, at least in comparison with the quality
+and variety of the best roman fonts. This was partly a consequence
+of the antiquity of the language and its consequent evolution in both
+writing and pronunciation: not only did the letterforms change over time,
+but they came to be adorned with a multitude of diacritical marks, a
+legacy of zealous scribes and grammarians anxious to preserve the
+pristine state of the language that lent them their prestige.
+
+In the early days we find that the few printers that attempted to cut
+Greek type generally ignored all this complexity, either disregarding
+the diacritics or casting them separately and setting them
+above each line of text. Some texts were printed in
+lowercase only; others would make do with roman capitals like `A' and
+even some lowercase roman glyphs, like `v' for `$n$'. (See figures
+1--12 in [Brit.~Mus.~1927], an excellent historical survey.)
+
+In 1495 Aldus Manutius introduced cursive greeks.
+They became a resounding success, as they reproduced the florid
+and idiosyncratic handwriting of the day, full of abbreviations
+and ligatures. The inordinate number of ligatures is in fact the
+most striking feature of such fonts: for example, Fell's ``Great
+Primer Greek'' [Morison 1967, p.~102] has sorts for many
+four-letter words and prefixes.
+
+Although skilfully typeset books using cursive fonts are undeniably
+beautiful (see [Brit.~Mus.~1927], figure 29), the use of so many
+ligatures was a nightmare for compositor and reader alike, since
+in some cases the component letters are virtually unidentifiable.
+Gradually the fonts were scaled down in size, but the practice
+of imitating handwriting remained until the end of the eighteenth
+century, when Bodoni, G\"oschen and Didot paved the way back to a
+more sober course.
+
+Still problems remained. Porson's greek [Mosley 1960], first used
+in 1826 and destined to become the standard of the English-speaking
+world, continues the illogical tradition of mixing upright capitals
+with slanted minuscules; in particular the blending of Greek and roman
+text leads to poor results (figure 1). Didot's design was somewhat
+more felicitous, and became standard in Italy, France and Greece itself
+(figure 2), but the type is narrow and irregular, bearing, according
+to Scholderer [Brit.~Mus.~1927, p.~14], the `malign mark' of Bodoni's
+greeks (which were admittedly not a match for his inspired romans).

+
+\midspace{1.2truein}
+\caption{\eightpoint Figure 2}
+
+(Incidentally, the different treatment of capitals established itself
+in mathematical typesetting. In English books, Greek capitals are the
+only math letters that are not slanted; in French and German books
+they conform with the rest. The Computer Modern Greek faces are
+based on Porson. They are, of course, meant for math; when used
+for text, as in [Wonneberger 1987], the results fall short of
+the perfection achievable with \TeX.)
+
+It was not until the beginning of this century that really
+well-designed Greek types became available, including Scholderer's
+`New Hellenic' type (figure 3), based on a pre-Aldine model,
+and the Monotype font shown in figure 4, a much improved version
+of Didot's design and perhaps the typeface most favored for
+high-quality printing in Greece during the last few decades.

+\heading Requirements \endheading
+
+My main motivation in designing a family of Greek fonts is the
+preparation of a Modern Greek--English dictionary. This in itself
+makes the design more exacting: the fonts should not only look good
+individually and in combination, but also blend well with Computer
+Modern fonts; there should be at least three main styles, different
+enough that no special effort to distinguish between them is required,
+even in small point size; and the typing should be as painless as
+possible on a standard (English) keyboard.
+This last condition is, of course, open to interpretation, but I
+define it to mean that each grapheme (letter, accent, etc.)~should
+require as few keystrokes as possible---generally one, but
+occasionally more, like accents in English.
+
+In esthetic terms there are a lot of details to work out, but the
+foundation has been laid. I follow loosely the type shown in figure 4,
+which shares several features with the Computer Modern roman:
+sharp contrast between thicks and thins, similar letter widths,
+and a wealth of texture and detail. (This is not surprising since
+the `modern' family of fonts goes back to Bodoni and Didot.)
+But it also has distinguishing features, which recapture some of the
+beauty of cursive writing: its strokes are more fluid, and there
+is no left-right symmetry (compare a roman `o' with a greek `$o$').
+
+Modern Greek has traditionally been typeset with the diacritic
+apparatus of ancient Greek, which is very rich: it contains two accents,
+the acute $'$ and the grave $`$, that can go over any vowel, plus one,
+the circumflex $~$, that can go over the vowels $ahiuw$; two so-called
+breathings $<>$, one of which goes over every vowel or diphthong
+in initial position; the diaeresis $"$, that can go over $i$ and $u$;
+and the iota subscript $|$, that can go under $ahw$. An accent
+plus a breathing, or an accent plus the dieresis, can coexist;
+furthermore any accent, breathing or accent-breathing combination
+can share a vowel with an iota subscript. Here, for example,
+are the 24 possible varieties of lowercase $a$:
+\display
+\hbox{$a 'a `a ~a <a <'a <`a <~a >a >'a >`a >~a
+a| 'a| `a| ~a| <a| <'a| <`a| <~a| >a| >'a| >`a| >~a|$}
+\display
+
+In the last several decades the tendency has been to get rid of these
+complications, and now the ``official'' system in use in Greece includes
+only one accent and the dieresis, without breathings or iota subscripts.
+Even though I work primarily with modern Greek, however, I thought
+it short-sighted not to include the whole apparatus, having in mind
+both classicists and those traditionalists who
+still prefer the three-accent system, as do some publishing houses.
+
+It was clear right away that these diacritics should be implemented as
+ligatures, not as \TeX\ accents, because in \TeX\ words that include
+accents cannot be hyphenated. This implied that 128 font
+positions were not enough. Fortunately \TeX\ and \MF\ are
+well equipped to handle 256-position fonts, though most device
+drivers are not (see the section `Other Problems').
+
+Following the one-keystroke-per-grapheme rule, then, one can conjure
+up the last alpha in the display above by typing |>~a|{\tt\char`\|},
+which accesses a four-character ligature. The remaining conventions
+for diacritics are: |'| and |`| for the acute and grave, respectively;
+|"| for the dieresis; and |<| for the rough breathing. (If you're
+wondering how to produce quotation marks, or $((e>isagwgik'a))$,
+it's by typing |((| and |))|.)
+
+\heading The Font Layout \endheading
+
+A further complication has to do with the letter sigma. According to
+Knuth [1980], the letter `s' is in a class by itself in terms of
+complexity of design; its Greek counterpart is similarly difficult, though
+for different reasons. A sigma in initial or medial position in the word
+is written $c$, but in final position it is written $s$. Since the
+alternation is entirely conditioned, it seemed a pity to require different
+characters in the \TeX\ file to represent the two varieties of sigma.
+
+The first solution I tried made no assumptions on the font. It
+consisted in making `s' an active character, which checked the next
+token and printed $c$ if it was a letter, $s$ otherwise. There were
+two drawbacks to this procedure: the letter `s' could not be used
+in control sequences, and the check was expensive. (It also didn't
+work when the next token was a control sequence that expanded to one
+or more letters.)
+
+A better idea is to save one position in the font for an
+invisible dummy character. All punctuation marks (and the space)
+are made active; they expand to the dummy end-of-word character,
+plus the punctuation character. An `s' by itself prints as $c$,
+while an `s' in ligature with the dummy---which is to say, at the end
+of a word---prints as $s$. All other letters yield themselves when
+in ligature with the dummy. This is still not ideal for two reasons:
+\TeX\ is always ``obeying spaces,'' and words separated by something
+other than punctuation or spaces (say |\par|) count as one. (But
+this might be the only practicable solution for the Hebrew alphabet,
+which has five chameleon letters.)
+
+The solution I chose avoids the drawbacks above, at the expense of
+several positions in the font. Namely, the font contains each of
+the possible combinations $sa$, $sb$, \dots, $sw$, which are
+automatically accessed as ligatures when the word contains `s'
+followed by a letter.

+
+With all the s\plus letter combinations and all the vowels with
+diacritics, it turns out that not even 256 characters are enough.
+Since I couldn't push the font size any further, I decided to
+eliminate some of the vowel\plus diacritic combinations. The obvious
+candidates were the combinations of breathings with grave accent,
+which can only occur in a restricted number of monosyllables, and
+thus can be typeset as accents, because no hyphenation is required
+anyway. So I made the characters |<| and |>| active. Depending on
+whether or not the next character is $`$, these active characters
+expand to an |\accent| or to a |\char|, the latter meant to form
+a ligature with what comes next. (Actually, things are not quite
+so simple. A breathing or accent over a capital vowel is
+traditionally written before the letter, so the |\accent| control
+sequence is only emitted if the following character is lowercase.)
+
+The complete layout of the fonts is shown on the next page. There
+are a few unfilled positions, two of which I'm saving for the digamma,
+whose design I haven't yet tackled.
+
+\heading Other Problems \endheading
+
+In order to write continuous text, I had to prepare a modern Greek
+hyphenation table, which I'm currently testing.
+The hyphenation of modern Greek follows closely that of ancient Greek,
+which is straightforward (that is, described by a fairly short set of
+rules) because Greek had originally a phonetic script---one letter
+for each phoneme and vice versa. This conservatism means that
+hyphenation does not necessarily occur between syllables, as in
+the word $stau-r'os$ `cross', now pronounced
+[sta\'{}vros]; but this apparently doesn't bother anyone.
+
+One difficulty, however, cannot be resolved by means of mechanical
+rules: the digraphs $mp$, $nt$ and $gk$ are sometimes pronounced as
+nasal\plus voiced stop, sometimes as voiced stop alone, depending on
+the word (also sometimes on the speaker). In the first case, the group
+can be split, but in the second, one should hyphenate before the group.
+This problem seems to be solvable only by trial and error.
+
+The last problem I want to discuss is that of device drivers.
+We have been using various |dvi|-to-PostScript drivers in Princeton,
+and I found that none of them would work with
+256-character fonts, even though both \TeX\ and PostScript are
+designed to handle such fonts. I was, however, able to adapt Nelson
+Beebe's excellent driver |dvialw| [Beebe 1987] after making only
+three changes, because the program is well written and well documented.
+I exhort all those who write |dvi| drivers to include 256-character
+fonts in their design, since they will certainly become more necessary
+as \TeX\ extends its reach around the world.

+
+In this document I hope to show that typesetting Greek in \TeX\
+using the \.{gr} family of fonts can be as easy as typesetting
+English text, and leads to equally good results.
+This is meant to be a tutorial, not an exhaustive discussion;
+some \TeX nical remarks that should be useful after the reader
+has acquired some familiarity with the fonts are printed in fine
+print.
+
+\heading
+The Alphabet
+\endheading
+
+In order to typeset Greek text, you need to go into ``Greek mode.''
+This is achieved by typing \.{\!begingreek} anywhere in your document;
+Greek mode will remain in effect until you type a matching \.{\!endgreek}.
+While in Greek mode, the letters `a' to `z' and `A' to `Z' come out
+as Greek letters, according to the following code:
+\display
+\hbox{\valign
+ {\hbox to 10pt{\hfil\strut$#$\hfil}&\hbox to 10pt{\hfil\strut\tt#\hfil}\cr
+ a&a\cr b&b\cr g&g\cr d&d\cr e&e\cr z&z\cr h&h\cr j&j\cr
+ i&i\cr k&k\cr l&l\cr m&m\cr n&n\cr x&x\cr o&o\cr p&p\cr
+ r&r\cr c&s\cr t&t\cr u&u\cr f&f\cr q&q\cr y&y\cr w&w\cr}}
+\enddisplay
+
+There is no digamma yet. The same character `s' will print as
+`$c$' or `$s$', depending on its position in a word.
+
+\begineight
+The system does this by accessing a ligature of `s' with any other
+letter that follows it. If, for some reason, you want to print
+an initial/medial sigma by itself (as in the table above), or
+at the end of a word, you should type `c'.
+\endeight
+
+Try to typeset some simple text now. Create a file
+containing the following lines:
+
+\beginverbatim
+\input greekmacros % where \begingreek and other commands are defined
+This is English text.
+\begingreek
+This is Greek text.
+\endgreek
+?endverbatim
+
+When you \TeX\ this file, you get the following gibberish:
+\display
+\hbox{
+This is English text.
+\begingreek
+This is Greek text.
+\endgreek
+}
+\enddisplay
+
+If you say \.{\!greekdelims} near the top of your file,
+the character \.{\$} can be used
+in place of both \.{\!begingreek} and \.{\!endgreek}. The control
+sequence \.{\!math} takes on the former meaning of \.{\$}.
+
+\heading
+Accents and Breathings
+\endheading
+
+To get an acute, grave or circumflex accent over a vowel,
+type \.{'}, \.{`} or \.{\~}, respectively, before the vowel.
+To get a rough or smooth breathing, type \.{<} or \.{>} before
+the vowel (or rho) and any accent that it may have. To get an iota
+subscript, type \.{|} {\it after\/} the vowel. A diaeresis is
+represented by \.{"}, and if accompanied by an accent it can come
+before or after the accent.
+
+For example, \hbox{\.{>en >arq\~h| >\~hn <o l'ogos}}
+gives \hbox{$>en >arq~h| >~hn <o l'ogos$}.
+Neat, ain't it?
+
+\begineight
+Accents and breathings, too, are typeset by means of ligatures: a
+vowel with a breathing, an accent and iota subscript, for example,
+is realized as a four-character ligature. The only exception is
+when a breathing is followed by a grave accent, in which case the
+breathing\plus accent combination is typeset as a \TeX\ \.{\!accent}
+over the vowel. This means that words containing such combinations
+cannot be hyphenated in (standard) \TeX; but this is not a problem
+because, with the exception of very rare cases of crasis, all such words
+are monosyllables.
+\endeight
+
+\heading
+Punctuation
+\endheading
+
+Here's the table of correspondences for punctuation:
+\display
+\hbox{\valign
+ {\hbox to 15pt{\hfil\strut$#$\hfil}&\hbox to 15pt{\hfil\strut\tt#\hfil}\cr
+ .&.\cr ,&,\cr ;&;\cr :&:\cr !&!\cr ?&?\cr ''&''\cr ((&((\cr ))&))\cr}}
+\enddisplay
+The last three entries represent the apostrophe and quotations marks.
+The other available non-letters are the ten digits, parentheses,
+brackets, hyphen, em- and en-dashes, slash, percent sign, asterisk,
+plus and equal signs. All of these are accessible in the same way as
+under plain \TeX. In a future release there will be tick marks for
+numbers (\math\hbox{$a$}'=1\math, \math{}_\prime\hbox{$a$}=1000\math).
+
+\heading
+Hyphenation
+\endheading
+
+A hyphenation table for both modern and ancient Greek is currently
+being debugged. For now one can use plain \TeX\ with its (English)
+hyphenation table, which gives the right results about 90\% of the
+time (amazing, isn't it?). Be sure to proofread your text carefully,
+unless you've turned hyphenation off.
+
+\begineight
+In standard \TeX, only one hyphenation dictionary can be used in
+a job. Thus, even with a Greek hyphenation table, a file that
+combines Greek and English text is likely to be incorrectly
+hyphenated. Michael Ferguson's extension to \TeX\ handles multiple
+hyphenation tables, and hyphenates words containing \.{\!accent}s
+(cf.~the previous fine print paragraph).
+\endeight
+
+\heading
+Interaction with other macros
+\endheading
+
+While in Greek mode you can do just about everything that you can
+outside: go into math mode, create boxes, alignments, and so on.
+The file \.{greekmacros.tex} sets things up so that in Greek mode
+the control sequences \.{\!tt} and \.{\!bf} switch to a
+typewriter and a bold Greek font, respectively: thus
+\.{\{\!tt s''>agap\~w\}} gives \hbox{$\tt s''>agap~w$}. (Try it.)
+On the other hand, there are no ``italic'' or slanted Greek fonts,
+so \.{\!it} and \.{\!sl} will give you the same fonts as outside
+Greek mode. The various constructions under
+\AmSTeX\ and \LaTeX\ for increasing or decreasing point sizes don't
+work yet; they will in a future release.
+
+The characters that form diacritics (\.{<}, \.{>},
+\.{'}, \.{`}, \.{\~}, \.{"} and \.{|}) are treated differently
+depending on whether or not you're in Greek mode. More exactly,
+under plain \TeX\ these characters (with the exception of
+\.{\~}) have a \.{\!catcode} of 12: they print as themselves,
+and they cannot appear in control words. But in Greek mode
+\.{'}, \.{`}, \.{\~}, \.{"} and \.{|} are ``letters'', that is,
+they have a \.{\!catcode} of 11, while \.{<} and \.{>} are
+active, with a \.{\!catcode} of 13. This may be important even
+for beginners because it means that \.{'}, for example, can be taken
+as part of a control word. Thus the sequence
+\beginverbatim
+\begingreek
+\line{wm'ega\hfil'alfa}
+\endgreek
+?endverbatim
+\noindent
+will cause an error message about an
+undefined control sequence \.{\!hfil'alfa}, instead of printing
+\display
+$\line{wm'ega\hfil 'alfa}$
+\enddisplay
+as you might expect. (I hope classicists will forgive this use
+of the modern Greek one-accent system.) The solution, of course,
+is to remember to add a blank after the \.{\!hfil}.
+
+\begineight
+A more subtle problem arises when you use Greek text in macro
+arguments, if the arguments are scanned while you're outside Greek
+mode. This is because \TeX\ assigns \.{\!catcode}s to tokens
+as it first reads them, so when the argument is plugged into
+the body of the macro the characters above have the wrong
+\.{\!catcode}. If the legendary Jonathan Horatio Quick were
+to write
+\display
+\hbox{\.{%
+\!def\!hellenize\#1\{\!begingreek \#1\!endgreek\}
+\!hellenize\{d'uo >`h tre\~is,\}}}
+\enddisplay
+he would be unpleasantly surprised by the following output:
+\display
+\def\hellenize#1{\begingreek #1\endgreek}
+\hbox{\hellenize{d'uo >`h tre~is,}}
+\enddisplay
+which can be explained as follows: the \.{\~}, which should be
+a letter, is seen as an active character, and expands to a blank
+as in plain \TeX; while the breathing, which should be active,
+is not, and in particular it doesn't do the right thing when
+next to the grave accent. Solutions to this problem require a
+bit of wizardry, and will not be discussed here; see, for example,
+Reinhard Wonneberger's article in the October, 1986 issue of
+{\it TUGboat}, especially pages 179--180.

+\centerline{INSTALLATION INSTRUCTIONS}
+
+\medskip
+
+(Note to non-UNIX sites: These instructions should be followed verbatim
+only on systems running UNIX. I've tried to make the instructions
+understandable to people without knowledge of UNIX, so that if you're
+familiar with your own operating system it should not be hard to
+figure out the right thing to do under it. If the separator between
+components of a file pathname is not `/', you should change the
+definition of \.{readfrom} in \.{grbase.mf}.
+
+See the \.{README} file for an important note concerning required
+METAFONT capabilities.)
+
+In order to make the fonts, you need an executable version of
+METAFONT, version 1.0 or newer, with the `plain' base preloaded
+(see p.~279 of {\it The METAFONTbook\/} if you're not familiar with this).
+You will also need the \.{cmbase.mf} file, which is distributed
+with METAFONT, unless you have an executable METAFONT with that
+file already preloaded. The shell script (batch file) \.{makefont}
+assumes that \.{cmmf} is an executable METAFONT with \.{cmbase.mf}
+preloaded; if you don't have that you can replace \.{cmmf} by
+\.{mf} in \.{makefont}. (Non-UNIX sites: you'll have to edit
+\.{makefont} anyway, as well as \.{testfont} and \.{makeall} below.
+In each case the comments inside the file should guide you in finding
+the right incantations under your operating system.)
+
+If METAFONT has never been used at your site before, you will
+also need to create a file \.{local.mf} and preload it together
+with \.{plain.mf}. (See pp.~278--9 of {\it The METAFONTbook}.)
+This file
+should contain the characteristics of the different output
+devices that you will generate fonts for. The parameters
+for many output devices can be found on page 269 of the November
+1987 issue of TUGboat; and two more devices (the Apple laserwriter
+and Sun workstation) which are not in that table can be found
+in \.{modes.mf} (in this distribution). The values in \.{modes.mf}
+are experimental; if you feel like fiddling with them and think
+you can get better results, let me know. In any case, your
+\.{local.mf} should contain mode definitions for all output devices
+you intend to use the fonts with, and it should be preloaded
+together with \.{plain.mf}, so that when you issue the command
+\.{mf} or \.{cmmf} all this information is already in memory.
+
+Next you should test one font by saying
+
+\smallskip
+\disp{makefont grreg10 [\angles{modename}]}
+\smallskip
+
+(where \angles{modename} stands for \.{alw} if you're generating
+for the laserwriter, for example; the default is
+\.{localmode}, which should be defined in \.{local.mf}).
+It will take a while to make the font, and when
+it's done you can look in \.{grreg10.log} to see if everything went
+smoothly. If everything is OK, move \.{grreg10.tfm}
+and \.{grreg10.NNNgf} to the system's \TeX\ font directory (often
+\.{/usr/lib/tex/fonts}) and do a test run:
+
+\smallskip
+\disp{\% tex}
+\disp{\angles{blurb...}}
+\disp{**\!font\!test=grreg10 \!test ABC \!end}
+\disp{\angles{more blurbs; hopefully no error messages}}
+\disp{\%}
+\smallskip
+
+The text typed during this test should be very simple, as above:
+no accents, ligatures, etc. If you got a \.{texput.dvi} file without
+problems, you should try to print it, using your local dvi driver.
+Some dvi drivers cannot read font files of the form \.{*.NNNgf},
+only those of the form \.{*.NNNpk}; you can use the utility
+\.{gftopk}, which comes with the METAFONT distribution, to carry
+out the conversion. If your driver can only read \.{*.NNNpxl} fonts,
+it's time to get a new one.
+
+Another problem with some dvi drivers is that they don't
+take 256 character fonts, although they should, since 256 characters
+is part of standard \TeX. (The reason is, presumably, that Computer
+Modern fonts only have 128 characters, and programmers were counting
+on all other fonts being similarly restricted.) To test this
+aspect of your driver, create a dvi file with a character in the
+range 128-255:
+
+\smallskip
+\disp{\% tex}
+\disp{\angles{blurb...}}
+\disp{**\!font\!test=grreg10 \!test 'a \!end}
+\disp{\angles{more blurbs}}
+\disp{\%}
+\smallskip
+
+When you try to print this, you may get an error message, or
+a core dump, or simply a blank page. If so, you will have to
+fix your driver or get a new one. Fixing your driver involves
+understanding fairly well the dvi format (carefully explained
+in {\it\TeX: The Program}), but should not be beyond anyone with
+a modicum of systems programming experience. Getting a driver
+that works is probably easier if you're well connected,
+electronically speaking. I recommend Nelson Beebe's family
+of drivers (page 41 of the April 1987 TUGboat). Here are
+some hints from Nelson Beebe for obtaining his drivers:

+
+Once you've got the driver working, you can type
+
+\smallskip
+\disp{testfont grreg10}
+\smallskip
+
+for a full-blown test of the font \.{grreg10}. This creates
+a dvi file \.{grtestfont.dvi} and moves it to \.{grreg10.dvi}, which you
+should then print.
+
+Finally, you can say
+
+\smallskip
+\disp{makeall [ \angles{modename} [ \angles{mag} ]]}
+\smallskip
+
+for all modes and magnifications desired. Don't forget to move
+the \.{*.tfm} and \.{*.NNNgf} files thus obtained to their destination
+directory.
+
+The last step is to TeX the user's manual page (\.{doc/readme.tex})
+and make it available to users.

+% Greek.sty
+% A latex style file for use with Silvio Levy's classical Greek fonts
+% (see TUGboat 9.1 (1988), pp. 20 ff.). The following style file
+% consists of Levy's own greekmac.tex macros unaltered, followed by
+% some macros published by R. Wonneberger and slightly modified
+% by D. Wujastyk, which fix a problem in using Greek accents in LaTeX
+% footnotes. See below for more explanation of the footnote stuff.
+%
+% Usage: \documentstyle[greek]{book} ... as normal. This makes all the
+% greekmac macros available, and fixes the footnote problem.

+% The following macros are taken from Reinhard Wonnenberger's
+% article "Chapter Mottos ..." in TUGboat 7(3), 1986, p.179. I (Dominik
+% Wujastyk) have edited out those bits in which Reinhard was altering
+% the default values of LaTeX to his own liking. If you want to do
+% that as well, you might prefer to do it in a separate style file.
+%
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% The following macros avoid the need to read the footnote text as
+% a parameter. They are taken from PLAIN.TEX.
+% LaTeX control sequences have been substituted for those from
+% PLAIN, and are marked thus: %LATEX
+%
+% \newinsert\footins
+% \def\footnote#1{\let\@sf\empty % parameter #2 (the text) is read later
+% \ifhmode\edef\@sf{\spacefactor\the\spacefactor}\/\fi

+%
+% Format the footnote label inside the footnote; based on book.sty:
+\def\@makefnlabel{\@@par \parindent 1em\noindent
+ \hbox to 1.8em{\hss$^{\@thefnmark}$}}
+%
+% From latex.tex, for comparison:
+% \long\def\@footnotetext#1{\insert\footins{\footnotesize
