Some things I had a hard time figuring out

There are a few measly things that took me some time to figure out in LaTeX (which probably says more about my intelligence than their difficulty). Here are some of them.

Essential packages
Use AMS-LaTeX with PostScript fonts + pdflatex.
\usepackage{latexsym,cmmib57}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage[psamsfonts]{amssymb,amsfonts,eucal}
Equation tags with (*) and such
In AMS-LaTeX, you can use \tag:
\begin{equation}\tag{*}
x=y^2
\end{equation}

Fonts

Fonts on MacOS X

You may feel like using some nice font in LaTeX, which is available to other MacOS X applications... Here is a record of what I did to get Bembo work in LaTeX documents. First problem: you need the Postscript font, but it's in a resource fork or stored in some other weird Macish way. Use Fondu. (If you never installed anything from the command prompt (Terminal), here is a hint: you may need to use sudo. Installing Fondu was easy: just ran configure and then sudo make install.) Now you can extract the .pfa or .pfb files: fondu ~/Library/Fonts/Bembo (the font file may be in the /Library/Fonts directory).

Second problem: make LaTeX find your fonts (metric and PostScript files). For Bembo, and a bunch of other popular fonts, it's fairly easy: download the appropriate package from CTAN: wget 'ftp://tug.ctan.org/tex-archive/fonts/psfonts/adobe/bembo.tar.gz'. Untar the package. For other fonts, you need to produce the necessary tfm fonts (fondu gives you a version, but that may not be good enough for purists): download the afm fonts from Adobe's ftp site, for example, and then transform the afm to tfm. (Usually, you need to pay for the Postscript fonts, but the metric files are freely downloadable.) Notice that there is a naming standard for the font files that dates back to the Stone Age: in the case of Bembo, all files start with pbb. (You may want to read the LaTeX font guides, and Adobe has a list of their font naming conventions also - no hyperlinks here, I don't have them at hand). The files are now in the tex, dvips, tfm, and vf directories. (Bembo in particular has a little glitch in it: the dvips/pbb.map has the wrong Postscript names, you need to replace ``MBembo'' with ``Bembo'' everywhere.) I assume you have a teTeX installation rooted at /usr/local/teTeX. Rename the Postscript font files as necessary: mv Bembo.pfb pbbr8a.pfb, etc., the .map files show what the names should be. Copy the files to the appropriate locations. I decided to put everything under /usr/local/teTeX/share/texmf.local. You may need to create the missing directories as shown here.

sudo mkdir -p /usr/local/teTeX/share/texmf.local/dvips/adobe
sudo cp dvips/* /usr/local/teTeX/share/texmf.local/dvips/adobe/
sudo mkdir -p /usr/local/teTeX/share/texmf.local/fonts/type1/adobe/bembo
sudo cp *.pfb /usr/local/teTeX/share/texmf.local/fonts/type1/adobe/bembo/
sudo mkdir -p /usr/local/teTeX/share/texmf.local/fonts/vf/adobe/bembo
sudo cp vf/* /usr/local/teTeX/share/texmf.local/fonts/vf/adobe/bembo/
sudo mkdir -p /usr/local/teTeX/share/texmf.local/fonts/tfm/adobe
sudo cp tfm/* /usr/local/teTeX/share/texmf.local/fonts/tfm/adobe/bembo/
sudo mkdir -p /usr/local/teTeX/share/texmf.local/tex/latex/adobe
sudo cp tex/* /usr/local/teTeX/share/texmf.local/tex/latex/adobe/

Make LaTeX and dvips aware of the new files: sudo texhash. Now you can use /usepackage{bembo} with latex and then do dvips -Ppbb. For pdflatex, you need to edit the config file of /usr/local/teTeX/share/texmf.local/pdftex/config/pdftex.cfg: add a line of map +pbb.map towards the end.

Luc's fonts

There are many free fonts available at the Web. Some of my favorites are found among Luc Devroye and Sandro Mazzucato's Postcript fonts. (The citations below are from Font samples page.)

(These instructions are for an older Unix machine I used to use.) I use these fonts with LaTeX and dvips, so the rest is the instructions how to setup files and environment variables. In order to use these fonts, you'll need to download at least a .pfa or .pfb file and a .tfm file for each font. The environment variable TFMFONTS must include the path to reach the .tfm files. The DVIPSFONTS variable should include the path to the .pf? files. Also, have a mapping file for fontnames and files. Mine looks like this:

Pach                    Pach                    <Pach.pfb
TropDePoils-Black       TropDePoils-Black       <TropDePoils-Black.pfb
Bazooka                 Bazooka                 <Bazooka.pfb
Waaiberg                Waaiberg                <Waaiberg.pfb

Add a pointer to it in your ~/.dvipsrc file as p +<your psfonts.map file> and set the DVIPSHEADERS environment variable to point to it. You can find more details in the DVIPS manual.

Pach
Janos Pach is a brilliant young Hungarian mathematician with a gorgeous handwriting. We obtained a sample written with a thick fountain pen when he gave a talk here at McGill, scanned it, and created a type 1 font by Sandro Mazzucato's software. The letter H shown here may not be the prettiest glyph, but one gets a good feeling for the smooth outlines that Sandro's oultline-optimization software leaves behind.
