At the moment, we put everything in ~/.TeXmacs, except for
temporary files, which are created using tmpnam (this is indeed unsafe).
Nevertheless, temporary files are mostly used for not-so-important data,
like the conversion of images. Also, we soon plan to put all temporary
files in ~/.TeXmacs/system. As to printing: we create a .ps files in
~/.TeXmacs/system and print it using the lpr or a user-defined command.
