Downloads all images from irasutoya.com
Clear out ~2.5GB of disk space and run java -jar irasutoya.jar, the irasutoya binary (still requires JVM installation) or for the enlightened, irasutoya.core/-main in the REPL. Images should be written to the output directory. You can use any SQLite client to read the irasutoya.db file left behind and read tag data or whatever.
