mu' HaqwI' comes in many flavours. Pick one for your OS:
To make updating mu' HaqwI's vocabulary easy, it is kept in a separate text file (usually called 'mutay.txt') that can be used by every version of the program. This makes it possible to update the vocabulary independent from the program itself.
Every distribution contains the vocabulary file that was current when that version was released. Even though you may have the current version of the program, the vocabulary that came with it may be outdated. In that case you should download the current vocabulary file from this page. To determine whether your vocabulary file is outdated, open your copy of the file with your favourite text editor and check the last date in the 'Change History' table against the date shown below.
