Maul is a DeskTop Publishing program that will handle posters, booklets and long documents. It also has a lot of documented interfaces, enabling developers to write their own import/export filters or extend/embed the program.
Maul Publisher started out several years ago, and went through many updates until v1.23 Then, the author started work on a Windows port, totally revising and optimising all his code, and now presented his v2.0 at Warpstock Europe.
The version available for download has the same number as the one distributed there, but already contains several important fixes. Although previous updates were all free, upgrading from v1.x to v2.x comes at a cost, since the package now also includes a hyphenation dictionary licensed from another firm.
