I was afraid you'd say that. Back on an FC5 system (where building's =20
much easier). After confusing myself and running "gnuplot" instead of =20=

"src/gnuplot" a bunch of times, I wrote this script:

#!/bin/sh
DATE=3D"$1"
cvs up -D$DATE && ./prepare && ./configure && make clean && make || =20
exit 1
src/gnuplot <<EOF || exit 1
set terminal pdf
set output "test-$DATE.pdf"
test
EOF
mv test-$DATE.pdf ~/public_html || exit 1
echo Check test-$DATE.pdf

20050701 works
20060101 doesn't
20051101 doesn't
20051001 works
20051017 doesn't
20051016 works

 =46rom there,

$ cvs up -r1.58 term/pdf.trm -> works
$ cvs up -r1.59 term/pdf.trm -> doesn't work
