i3wm).

*Tested on*:

* Examples
Run =cetus help= to get the usage printed & =cetus <command> <service> -help= to get
the flags for that particular service.

#+BEGIN_SRC sh
# set today's image as background
cetus set <service>  # <service>: apod, bpod

# set a random apod image as background
cetus set apod -random

# send a desktop notification
cetus <command> <service> -notify # <command>: set, fetch

* Installation
** Pre-built binaries
Pre-built binaries are available for OpenBSD, FreeBSD, NetBSD, DragonFly BSD,
Linux & macOS.

If you don't understand what this command does then don't run it. It doesn't
download the binary, it will just print the steps to install cetus & you have to
run those commands manually.
*** v0.6.4
*Note for OpenBSD users*: If you are using GNOME, Unity, LXDE or Pantheon then
this version may not work, due to unveil. This probably has been fixed in
v0.6.7, compile it.

#+BEGIN_SRC sh
curl -s https://tildegit.org/andinus/cetus/raw/tag/v0.6.4/scripts/install.sh | sh
#+END_SRC
*** v0.6.0
*Warning*: Don't use random flag on BPOD, it has been disabled in v0.6.1 but
v0.6.0 will cause issues if random flag is used with BPOD. This was fixed in
newer versions.

=cetus set bpod -random # don't do this=
