+Subject: inverse limit symbol
+
+I've been trying to make an "inverse limit" symbol. This should be a usual
+lim, with a left-pointing arrow under it, and it should be a "math operator
+with limits", that is, one should be able to write something like \ilim_n
+and get
+
+ lim
+ <--
+ n
+
+with, of course, the right spacing and so on.
+
+I've been trying to build on LaTeX with the AMS macros to do this. So far,
+my attempts have come out pretty bad. The first was
+
+\DeclareMathOperator*{\ilim}{\underleftarrow{\mathrm{lim}}}
+
+which puts the arrow far too close to the "lim". Plus, the arrow doesn't
+come out straight!
+
+Then I tried something like this:
+
+\newcommand{\ilim}[1]{%
+ \displaystyle{%
+ \lim_{\genfrac{}{}{0pt}{}{\longleftarrow}{\scriptstyle #1}} }\;}
+
+which sort of does it by brute force (and requires the "wrong" syntax
+\ilim{n}, but I can live with that). The arrow doesn't look right, however:
+it seems to be broken in the middle.
+
+Before I spend more time on this, I thought I'd check... perhaps someone
+out there has already solved it. Any suggestions?

+Subject: type1 version of ibycus polytonic greek
+
+A Type1 version of the Ibycus Greek font (regular weight only) is
+available on orhan.classics.washington.edu, in the directory
+/ftp/pub/tex. The files are bundled into either psibycus.tgz
+or psibycus.zip, to suit the convenience of both the elect and the
+infidel. This is a preliminary release, because the font is still
+largely unhinted. I will ultimately provide a rather thorough
+set of hints, since the primary purpose for making up this font
+was to get away from the crude bitmap scaling that is all you
+can get out of PDF readers. Hinting, however, is even worse than
+filing matrices. It is a soul-destroying bore, and I cannot do
+very much of it at any given session. The absence of hints will
+not be noticed at resolutions of 600dpi and above. The font has a
+private UniqueID in the open range for now, but a registered
+UniqueID will be applied for.
+
+The original METAFONT realization of ibycus4 remains the controlling
+form of the font. The TeX user will see absolutely no difference
+in the set-widths of the Type1 font because the TFM file for it is
+exactly the same as the TFM file for the METAFONT version. (In a
+Unix environment, they could be joined by hard or symbolic links.)
+
+The Type1 control points have been derived from METAFONT log output
+generated by "tracingspecs". This is not impossible, as has sometimes
+been claimed, but it does take work.
+
+The bundle consists of:
+
+1. IbycusHTG-Regular.pfa ( = fibr.pfa = IBYHTGR_.PFB ).
+ The character designs are Silvio Levi's. Some small differences
+ in accent positioning and vertical positioning on the classic
+ METAFONT typeface grid have been allowed. My own lowercase lunate
+ sigma has been improved. These changes will ultimately be read
+ back into the ibycus4 METAFONT source.
+
+2. fibr.tfm (identical with fibr84.tfm). The use of the Type1 font
+ is specified by calling on fibr, rather than fibr84. Obliqued and
+ bold versions of the font are still exclusively METAFONT.
+ They will continue to be invoked as fibo84[89]? and fibb84[89]?
+ until I make up Type1 versions of them (if I ever do).
+
+3. fibr.vf, which serves to provide a reference into a dvips map
+ file. The raw TFM for this VF file is fibr84.tfm, which has the
+ interesting effect of making METAFONT generated PK files a
+ fail-safe alternative when the dvips map lookup fails.
+ The checksums for fibr.tfm fibr84.tfm and fibr.vf are identical.
+ This is arbitrary, since fibr.vf has integer escapement values
+ rounded from the METAFONT values in the tfm files.
+
+4. config.iby and iby.map. The iby.map file shows how to associate
+ fibr84 with IbycusHTG-Regular.
+ fibr84 IbycusHTG-Regular <IbycusHTG-Regular.pfa
+ or
+ fibr84 IbycusHTG-Regular <fibr.pfa
+ This line can be copied into psfonts.map for general use.
+
+5. IbycusHTG-Regular.afm and IbycusHTG.enc. These are provided for
+ information only. The AFM file contains only the character info
+ and the pair-kerning data. There is no point in going further
+ since the Adobe convention for AFM is incapable of specifying the
+ ligature sequences needed for ibycus4. The encoding file could
+ supply both ligatures and pair-kerns, but to what purpose?
+
+6. Various TeX input files rewritten to use the fibr invocation in
+ place of the fibr84 invocation. (This is the only change that
+ users will need to make, other than installing the above files in
+ the TEXMF directory tree).
+
+IbycusHTG-Regular is licensed without charge for use in the creation of
+documents in all media, in accordance with the included copyright
+notice. Users are welcome and indeed encouraged to adapt the font
+to other typesetting systems. Note that iota subscript is applied to
+the affected vowel as a following zero-width character kerned
+drastically to the left. (Other well-known Polytonic Greek fonts
+do the same thing. This trick saves many, many glyph spaces for more
+constructive use.)
