Introduction
Not all of the Chinese input tables are actually free for Linux/BSD to distribute. So of them do, but others may have additional term and conditional attach to them, like no commercial use, or have to contact the author for authorization.
Some of the table authors are not known or uncontactable.
Note: Chinese intellect property office does not reveal the expire date.
Zhuyin is not included, as without end-key or other state support, it does not work well in ibus-table.
