# This TeXLive package uses libpaper(1). However, some older programs included
# in TeXLive are not libpaper aware and thus need individual configuration.
# The programs and the config file wrt. ${prefix}/share/texmf/dist/ are:

dvips         dvips/config/config.ps
				Just move the definition block of the papersize you want
				to be the default to the top of the defintion list, i.e. right
				below the "% emacs-page" line 
dvipdfmx      dvipdfmx/dvipdfmx.cfg
				Search for 'papersize-spec' and replace a4 with the default you
				want. E.g.: gsed -i -e '/^p / s@a4@letter@' $cfg
pdftex        tex/generic/config/pdftexconfig.tex
				Finde the line '% paper size settings' and set the default
				pdfpagewidth and height to use in the 2 lines below.
xdvi          xdvi/XDvi
				Search for '*paper:' and replace a4 with the default you want.
				E.g.  gsed -i -e '/^\*paper:/ s@a4@letter@' $cfg
context       tex/context/user/cont-sys.tex
				Search for papersize and replace corresponding values.
psutils       psutils/paper.cfg
				Similar to dvipdfmx.

# You may also try texconfig(1) to adjust those settings a little bit easier.
