cpio and rpm

I'm trying to submit tools and libraries into source control, and the tools (such as glibc) arrive in rpm's. Instead of installing them (which is what I don't want to do), I'm ripping the contents out. Of course, rpm doesn't give you an easy way to do that.

But I have determined the correct syntax to do it, as rpm's are really cpio files:

rpm2cpio rpmfile.rpm | cpio -id

checkstyle and phoning home

I noticed that everytime checkstyle runs it contacts www.puppycrawl.com to get its DTD. This is annoying...

I thought it was a bug in the checkstyle code, but it turns out I put the wrong DTD identifier at the top of all the checkstyle config files. Once I fixed that, it stopped phoning home.
