DESCRIPTION

16       "nbdkit-example4-plugin" is an example nbdkit(1) plugin written in
17       Perl.
18
19       The "size=N" parameter is required.  It specifies the disk size in
20       bytes.  A single disk image, initially all zeroes, is created and can
21       be read and written by all clients.  When nbdkit shuts down the disk
22       image is thrown away.
23
24       Mainly this is useful for testing and as an example of nbdkit plugins
25       written in Perl.  You should also read nbdkit-plugin(3) and
26       nbdkit-perl-plugin(3).  Note that nbdkit plugins may be written in C or
27       other scripting languages.
