Last change on this file since 103131 was 99038, checked in by vboxsync, 19 months ago

manual: Got rid of the correct_reference_targets Makefile-file rule, the new tactic is to scan the checked in .dita-files and .xml-files, store the id->filename mappings in file, and apply them as part of the refentry->dita conversion recipe for each individual Docbook-file. Use pattern rules for copying files to the staging area. bugref:10302
