New multi-part document mechanism (1.0.5.6 – 1.0.5.7)

Previous versions of TeXmacs provided the “project” mechanism for dealing with large documents like books. In the new version, any large structured document can be transformed into a multi-part document whose individual parts can be viewed and edited in an efficient way (see Document→Part). Former multi-file projects are deprecated although still supported. They can be transformed into multi-part documents using Tools→Project→Expand inclusions. A new multi-part document corresponds to a single file.
