Last change on this file was 2, checked in by jkacer, 18 years ago

Added all DocBook Framework stuff:

  • DocBook DTD
  • Transformation software FOP 0.20.5 and Saxon 6
  • XSL styles
  • Rexx scripts

Also added some WarpIN-related stuff for creation of WarpIN installation packages.
This state corresponds to version 1.0.0 from November 2005, just slightly modified to carry versioning information (Rexx scripts).
