How to make custom dictionary for Hunspell

I have a question about building a custom dictionary for hunspell. I'm using a general English dictionary and affix file right now. How can I add user-specified words to that dictionary for each of my users?

What is a custom dictionary?

A Custom Dictionary is a list of words within Microsoft Word created by you. By placing a word on this list you are in effect saying to Microsoft Word, "If you see this word in a document, don't mark it as misspelled." The Custom Dictionary is integrated with the Spell checker, so it is easy to add and delete words.

create your own word-list and affix file for your language, if that doesn't exist. Well, for papiamentu - Curaçao's native language - such dictionary doesn't exist. But I had a hard time finding out how to create such files, so I am documenting it here: http://www.suares.com/index.php?page_id=25&news_id=233
