This is the pyxattr module, a Python extension module which gives access to the extended attributes for filesystem objects available in some operating systems.
pyxattr has been written and tested on Linux, kernel v2.4 or later, with XFS filesystems; ext2/ext3 should work also. If any other platform implements the same behavior, pyxattr could be used.
You need to have the attr library (including development headers; most distributions should have this, under various names) and setuptools installed in order to build and install the module.
