283We use it to implement a "distributed selection mechanism", which just
284means that one command uploads the file to a remote server, and another
285reads it.
286
287The commands can be set using the C<URxvt.remote-selection.store> and
288C<URxvt.remote-selection.fetch> resources. The first should read the
289selection to store from STDIN (always in UTF-8), the second should provide
290the selection data on STDOUT (also in UTF-8).
