 = cluster-deploy.sh =
 
 Deploy one or more files in parallel on every host of the hosts' list.
+The files are copied in the remote user's home directory.
+
 By default, the files are transfered one by one, to be sure to notice
 the errors for each file (bad permissions, out of space, etc.), but the
 -P option allows to transfer them all together.
 
-Dependency: parallel-scp (pscp)
+While it is possible to transfer directories with the default option, to
+synchronise directories one would rather use the -r option, that uses
+prsync rather than pscp to transfer the files. With the -R option, the
+remote files that are not in the local copy will be deleted (rsync's
+--delete option). With both options, the transfer is done with rsync's
+-a (archive) option.
+
+Please note that unlike rsync, prsync cannot handle multiple local
+files, therefore the -P option is ignored when passed along with -r or
+-R.
+
+Dependencies: parallel-scp (pscp), parallel-rsync (prsync)
