svg2png is a perl script to convert the svg files in the current directory into png images, doing the conversion only if the svg file is newer than its corresponding png.
Simply run ./svg2png in the working directory.
On 6 January (2024), I had to amend this 2008 script with the line
print MyMakefile "\tinkscape -h 7200 -b white -o $file.png $file \n\n";
since the export option is not -e anymore but -o. I also added the -b=white option to force white background. This makes version svg2png v°0.2.
