can we make "aria2c -S some.torrent" to show all the metainfo from the torrent file, includig the creation date, comment, creation software, exact filesizes (not just 700Mib, but 734003200bytes). It is neither hard to do, nor will it congest the output, thuouhg it will improve the usefullness of aria2 considerably.
About file size, I have been also concerned about that. I think the abbreviation form of size(like 22MiB) is easy to read for human, but if the file size in a few GiB, then the hidden size is increasing, so it is not good. I think just printing raw size is very hard to read, so I will put comma in every 3 digit, like 1,300,300 bytes.
I think additional attribute in torrent file is: comment , comment.utf-8, created by and creation date.
Currently aria2 doesn't parse these values(since it is irrelevant to download), I need to add the parsing code for them.
As you wrote, it is not hard to implement this.
Fixed in r1500 and r1501.
