setxattrs.c

/*
 setxattrs - bubbaATbubba.org
 
 Properly sets sparse bundle extended attributes lost when rsyncing
 sparse bundle data to a platform that does not support extended
 attributes.  This is only need when restoring/retrieving the
 bundle.
 
 To use, sync/copy all bundle files, then run this tool on the
 sparse bundle:
 % gcc -o setxattrs setxattrs.c
 % ./setxattrs mybackup.sparsebundle
 % xattr -l mybackup.sparsebundle
