texmf.local for Fink-installed latex

This note assumes you have a working Fink installation of tetex on your Mac.

To install the local latex classes, such as infletr, which produces letters on informatics letterheads (School, Institutes, Graduate School, ITO, etc.):

In a terminal window on your mac, do (don't type the % that is supposed to represent the shell prompt)
% cd /sw/etc/texmf.local/tex/
then the following
% sudo scp -r user@host.inf.ed.ac.uk:/usr/local/share/texmf/tex/latex .
Here user is your UUN, host is any dice machine you have access to. You will get asked for your mac password (for the sudo) and then, unless you have a valid Kerberos ticket, your dice password (for the scp access to your dice machine).
Then let the latex installation cache information about the classes you've installed.
% sudo texhash

Fink doesn't interfere with texmf.local, so you can use Fink to update your latex installation without destroying your copy of the informatics classes — but you should use rsync from time-to time to keep your copy up-to-date.

% sudo rsync -az --delete user@host.inf.ed.ac.uk:/usr/local/share/texmf/tex/latex /sw/etc/texmf.local/tex/latex
% sudo texhash
