Mac Files obtained with PFA/PFB Convert, in OzTeX's tex extras,

prodint.sit.hqx 	Stuffed and binhexed (by Alladin Dropstuff 5.1.2), contains:

prodint			A Mac postscript font (lwfn file, with "laser writer font" icon)
prodint Suitcase	A font suitcase (i.e., a screenfont: bitmap+font description)



========================================================================

To install the font for LaTeX in a Unix system do:


1. Copy "prodint.tfm" and "prodint.pfb" where the LaTeX fonts live.

2. Add to your "fonts.map" (usualy in "/usr/share/texmf/dvips/config")
   the entry:

prodint prodint < prodint.pfb


3. Copy "prodint.sty" where LaTeX can see it.


4. Execute `mktexlsr' or whatever you need to do to update the ls-R file.


"prodint.sty" defines the product-integral symbol in three sizes:

\prodi   ----- text
\Prodi   ----- display
\PRODI   ----- big

check "prodint.ps" to see how these look like. 

You can generate "prodint.ps" without installing the LaTeX prodint
files by typing

    latex prodint; dvips -o prodint.ps -P prodint prodint

in this directory.

========================================================================

To install the font for LaTeX in Mac OS 9 do:

1.  Throw prodint.sit.hqx onto the Stuffit Expander icon.  This produces a 
folder, prodint, containing two files:

prodint			A postscript font (with "laser printer font" icon)
prodint Suitcase	A font suitcase (bitmap+font description)

Put   prodint    and    prodint Suitcase   into your System's font folder.


2. What kind of TeX do you have?  I use OzTeX.   What I do: 

Add to the file "psfonts.map" which resides in   OzTeX/TeX/DVIPS/Inputs    the line:

prodint prodint          <prodint

This takes care that dvips knows about prodint.


Add to the file "Local" which resides in   OzTeX   the line:

prodint   prodint        <prodint           prodint        nil

This takes care that OzTeX's dvi viewer knows about prodint.


3. Copy "prodint.sty" where OzTeX can see it.


4. Copy "prodint.tfm" where OzTeX can see it.


"prodint.sty" define the product-integral symbol in three sizes:

\prodi   ----- text
\Prodi   ----- display
\PRODI   ----- big

check "prodint.ps" to see how these look like. 


========================================================================

To install the font for LaTeX in Mac OS X do:

Something between the UNIX and Mac installations! It is easy, and I have done
it for CMacTeX and for TeXShop. Send me an email if you want help.
CMacTeX understands Mac postscript fonts (with the laser writer icon, so-called
lwfn - laser writer font - files). TeXShop only knows about pfb files.
To use pdftex you must tell pdftex.cfg about the prodint.map file, where
the relevant font definition is made. The file prodint.map should contain
the single line

prodint   prodint        <prodint

or

prodint   prodint        <prodint.pfb

=======================================================================

Another UNIX installation (Utrecht):

1. Unpack the tar file.

In directory  /usr/local/TeX/texmf/fonts/afm ,  make  subdirectory  prodint  and put 
prodint.afm  in it.

In directory  /usr/local/TeX/texmf/fonts/tfm ,  make  subdirectory  prodint , and put
prodint.tfm  in it.

In directory  /usr/local/TeX/texmf/fonts/type1 ,  make subdirectory  prodint , and put
prodint.pfb  in it.

Put  prodint.tex  en  prodint.sty  in
/usr/local/TeX/texmf/tex/local_styles


2. Make Type1 fonts known to TeX .

To make use of Type1 fonts, include all pfb file information in the 
following .map files

For dvips, in /usr/local/TeX/texmf/dvips/config/psfonts.map ,  add the line:

prodint prodint < prodint.pfb  

For dvipdfm,  in /usr/local/Tex/texmf/pdftex/config/psfonts.map, add the same line.

With the unix command 

texconfig rehash 

a new TeX file index is created  (ls-R file), so TeX can actually find the new fonts and files.
