** Writing completion functions using _describe
The _describe function can be used for simple completions where the order and position of the options/arguments is
not important. You just need to create an array parameter to hold the options & their descriptions, and then pass
the parameter name as an argument to _describe, e.g. like this:
#+BEGIN_SRC sh
local -a options
options=('-c:description for -c opt' '-d:description for -d opt')
_describe 'values' options
#+END_SRC
You can use several different lists separated by -- e.g. like this:
#+BEGIN_SRC sh
local -a options arguments
options=('-c:description for -c opt' '-d:description for -d opt')
arguments=('e:description for e arg' 'f:description for f arg')
_describe 'values' options -- arguments

** Writing completion functions using _arguments
The _arguments function makes it easy to create completion functions.
