The program that makes these slides makes many shell calls
It converts many text files to HTML
The conversion is slow
So it does the conversion only if the text file has changed:
if (! -e ".bak/$filename" || system("cmp -s $filename .bak/$filename")) {
print STDERR "*";
push @SLIDES, $filename;
}
# later, convert each file in @SLIDES from text to HTML
