## PDF files.

## The page layouts (a4/letter) are written directly in the .tex files.

cs-refcard.pdf cs-dired-ref.pdf cs-survival.pdf sk-refcard.pdf \
sk-dired-ref.pdf sk-survival.pdf: %.pdf:	%.tex
	if pdfcsplain --version > /dev/null 2> /dev/null; then \
	  pdfcsplain $<; \
	else \
	  csplain "\pdfoutput=1\input $<"; \
	fi

## Some versions of pdfmex seem to create dvi by default, hence output-format.
pl-refcard.pdf: %.pdf: %.tex
	if ! kpsewhich -format=fmt mex > /dev/null && \
	  ! pdfmex --version > /dev/null 2> /dev/null; then \
	  echo "No mex format found."; false; \

## dvi files.

	csplain $<

	tex $<


## PostScript files.

## Note that some of the tex files (refcard, de-refcard, fr-refcard,
## pt-br-refcard) have settings for letter or a4 paper. Following are
## the default paper sizes (letter for English, A4 for translations).
## FIXME orgcard.ps does not fit on letter (see orgcard.tex).

## A4, landscape.
de-refcard.ps fr-refcard.ps pt-br-refcard.ps orgcard.ps: %.ps: %.dvi
	dvips -t a4 -t landscape $< -o $@

## A4, portrait.
