Apologies for opening an old thread.  I didn't think it was appropriate 
starting a new one and this post is mainly for the sake of completeness.

The following lines were removed from pdf2swf.c in swftools 0.9.0 and 
they were the root cause of my "problem":

-- lines 643 to 646

if(info_only) {
        show_info(driver, filename);
        return 0;
}

If you add them back into pdf2swf.c and recompile swftools, you should 
be able to get info to output to stdout by default when pdf2swf -I is used.

Regarding Mr. Pugh's final comment, it would still be possible to output 
to a file with the code snippet above included in pdf2swf.c, issue:

pdf2swf -I file.pdf -o data.xml

[I wouldn't personally use xml as an output file though to store the 
results of pdf2swf -I though]

Many thanks for this remarkable tool.
