Assuming you have the completion system already loaded, the following is
a fairly standard way of doing it.  The "_wanted" business makes it fit
in with the standard conventions.

_Theme() {

  local -a themes
  themes=($(<${__themes_dir}/list-of-themes.txt))
  _wanted tests expl -a themes
}
compdef _Theme Theme
