Changes

Here we collect several tips and tricks for dealing with right-to-left (RTL) texts as well as BiDi (bidirectional) texts. The large number of hooks in different commands makes it possible to use CONTEXT's support for such documents. However, there are limitations and/or bugs, as well. Everything here is tested in MkIV and we recommend that you try one of the most recent versions since certain bugs are fixed and features are added only in the beta. All the credit should go to Hans, Wolfgang and others who respond to questions on the mailing list.
