In particular,+this provides access to extended attributes on ext3/4 and xfs on Linux (as well+as other filesystems that support this interface). For more information about+extended attributes, see the man page for attr(5).++To build this code, you'll need to have the libattr development headers+installed. On Fedora/RHEL the package name is `libattr-devel`. On Debian/Ubuntu+the package name is `attr-dev`.++You can find the latest stable version of this code on+[HackageDB](http://hackage.haskell.org/packages/hackage.html).
