@kobook, it depends on what operating system you use.
I use SQL Expert Personal 4.2 on Windows, and the sqlite3 CLI tool on Kobo itself.
You can get the sqlite3 binary from helour's post's attachment for example:

Get AllInOne-sk.tgz and it's there.
You can also read the scripts contained within to learn how to create an automated upgrade file to add the dictionary, I did that myself, (thank you helour!).
