 /*
  * rcopy-repeatedly
+ *
+ *   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.
+ *
+ *   See the --help for options.
