+ copy-in local [local ...] /remotedir
+
+C<copy-in> copies local files or directories recursively into the disk
+image, placing them in the directory called C</remotedir> (which must
+exist). This guestfish meta-command turns into a sequence of
+L</tar-in> and other commands as necessary.
+
+Multiple local files and directories can be specified, but the last
+parameter must always be a remote directory. Wildcards cannot be
+used.
+
+=head2 copy-out
+
+ copy-out remote [remote ...] localdir
+
+C<copy-out> copies remote files or directories recursively out of the
+disk image, placing them on the host disk in a local directory called
+C<localdir> (which must exist). This guestfish meta-command turns
+into a sequence of L</download>, L</tar-out> and other commands as
+necessary.
+
+Multiple remote files and directories can be specified, but the last
+parameter must always be a local directory. To download to the
+current directory, use C<.> as in:
+
+ copy-out /home .
+
+Wildcards cannot be used in the ordinary command, but you can use
+this with the help of L</glob> like this:
+
+ glob copy-out /home/* .
