 This package provides various dictionary files, such as `SKK-JISYO.zipcode',
 `SKK-JISYO.fullname', `SKK-JISYO.law', `SKK-JISYO.M', `SKK-JISYO.S', and
 so on, except the large size dictionary file `SKK-JISYO.L' provided by
 the skkdic package, for SKK Japanese input systems.

 To merge or edit dictionaries, install the skktools package. To use
 dictionaries more conveniently, several SKK dictionary servers are
