+/*
+ * Enhanced OS X and Netatalk compatibility
+ * ========================================
+ *
+ * This modules takes advantage of vfs_streams_xattr and
+ * vfs_catia. VFS modules vfs_fruit and vfs_streams_xattr must be
+ * loaded in the correct order:
+ *
+ * vfs modules = catia fruit streams_xattr
+ *
+ * The module intercepts the OS X special streams "AFP_AfpInfo" and
+ * "AFP_Resource" and handles them in a special way. All other named
+ * streams are deferred to vfs_streams_xattr.
+ *
+ * The OS X client maps all NTFS illegal characters to the Unicode
+ * private range. This module optionally stores the charcters using
+ * their native ASCII encoding using vfs_catia. If you're not enabling
+ * this feature, you can skip catia from vfs modules.
+ *
+ * Finally, open modes are optionally checked against Netatalk AFP
+ * share modes.
+ *
+ * The "AFP_AfpInfo" named stream is a binary blob containing OS X
+ * extended metadata for files and directories. This module optionally
+ * reads and stores this metadata in a way compatible with Netatalk 3
+ * which stores the metadata in an EA "org.netatalk.metadata". Cf
+ * source3/include/MacExtensions.h for a description of the binary
+ * blobs content.
+ *
+ * The "AFP_Resource" named stream may be arbitrarily large, thus it
+ * can't be stored in an xattr on most filesystem. ZFS on Solaris is
+ * the only available filesystem where xattrs can be of any size and
+ * the OS supports using the file APIs for xattrs.
+ *
+ * The AFP_Resource stream is stored in an AppleDouble file prepending
+ * "._" to the filename. On Solaris with ZFS the stream is optionally
+ * stored in an EA "org.netatalk.ressource".
+ *
+ *
+ * Extended Attributes
+ * ===================
+ *
+ * The OS X SMB client sends xattrs as ADS too. For xattr interop with
+ * other protocols you may want to adjust the xattr names the VFS
+ * module vfs_streams_xattr uses for storing ADS's. This defaults to
+ * user.DosStream.ADS_NAME:$DATA and can be changed by specifying
+ * these module parameters:
+ *
+ * streams_xattr:prefix = user.
+ * streams_xattr:store_stream_type = false
+ *
+ *
+ * TODO
+ * ====
+ *
+ * - log diagnostic if any needed VFS module is not loaded
+ * (eg with lp_vfs_objects())
+ * - add tests
