+/*
+Package striper contains a set of wrappers around Ceph's libradosstriper API.
+
+The Striper type supports synchronous operations to read and write data,
+as well as read and manipulate xattrs. Note that a striped object will
+consist of one or more objects in RADOS.
+
+There is no object list API in libradosstriper. Listing objects must be done
+using the base RADOS APIs. Striped objects will be stored in RADOS using the
+provided Striped Object ID (soid) suffixed by a dot (.) and a 16 byte
+0-prefixed hex number (for example, "foo.0000000000000000" or
+"bar.000000000000000a"). The object suffixed with ".0000000000000000" is the
+0-index stripe and will also possess striper specific xattrs (see the [ceph
+libradosstriper implementation] for a list) that are hidden from the
+libradosstriper xattr APIs.  You can use the name and/or these striper xattrs
+to distinguish a striped object from a non-striped RADOS object.
