cowdancer allows copy-on-write file access. You can copy a full tree
using hard links, and cowdancer will create a new copy when you need to
write to a file. It's completely implemented in userland, and should run
on most Linux filesystems.

This release adds a workaround for the coreutils 5.3.0 change to the
"stat" command. The COWDANCER_DEBUG environment variable can now be used
to obtain debugging messages.
It is now possible to run pbuilder 0.130. A regression test suite was added. Symbollic links are now supported and fopen/fopen64 is handled. COW is only performed on regular files. The tool no longer tries to cross device boundaries when creating the ilink list.
