+ * You say rcopy-repeatedly local-file user@host:remote-file
+ * and it polls for changes to local-file and copies them to
+ * remote-file. rcopy-repeatedly must be installed at the far end.
+ * You can copy in either direction but not between two remote
+ * locations.
+ *
+ * Limitations:
+ * * Cannot cope with files which are modified between us opening
+ * and statting them for the first time; if the file shrinks
+ * we may bomb out. Workaround: use rename-in-place.
+ * * When transferring large files, bandwidth limiter will
+ * be `lumpy' as the whole file is transferred and then we
+ * sleep.
+ * * Cannot copy between two local files. Workaround: a symlink
+ * (but presumably there was some reason you weren't doing that)
+ * * No ability to synchronise more than just exactly one file
+ * * Polls. It would be nice to use inotify or something.
+ *
+ * Inherent limitations:
+ * * Can only copy plain files.
