Currently, the documentation (man page, aspell --help, and the HTML manual) provides an extensive information on installation, command-line options, etc. However, it provides no end-user documentation. There is no explanation that the choice "1)" through "9)" are possible spelling suggestion what is the difference between "i)Ignore" and "I)Ignore All" and between "a)Add" and "l)Add Lower" etc. In addition to making its way to man pages (a *nix user first instinct at finding documentation is to normally to look up a man page), to be really user-friendly there should be an additional option "?)Help" as one of the choices.
