Hi, I've just created a patch, which enables splitter to read .bz2 compressed files directly without need for external decompressing. This eases live for me, as I generally get my osm data from geofabrik, which is bzip2 compressed. It uses the CBzip2InputStream class from org.apache.tools.bzip2.* If you apply only part a of the patch, then you will need a jar file with this class in your classpath. You can get it e.g. at http://www.kohsuke.org/bzip2/ If you apply part b additionally, then it contains all you need. But I absolutely don't know if the apache license, which is valid for the CBzip2InputStream class allows including in other projects. Therefore I have splitted the patch into two parts. Please comment, should this patch be commited to svn? Greetings, Johann
