#
# This slightly messy makefile transforms the DocBook XML source for the
# user manual into presentation output. We support two targets:
#
#   -- UserManual.pdf, generated by LaTex
#
#   -- VirtualBox.chm
#
#   Both files end up in PATH_STAGE_BIN.
#
#   Both targets indirectly depend on the XML files in this directory;
#   "indirectly" because we first copy them to PATH_TARGET and hack them
#   up a bit for variable substitution and such (see below).
#   The toolchains are roughly like this:
#
#   -- PDF file via Apache FOP: pre-process the XML files in PATH_TARGET,
#      then create a .FO file (another XML format for "formatted objects")
#      via xsltproc, then feed the .FO file to Apache FOP to create the PDF.
#
#   -- PDF file via LaTeX: pre-process the XML files in PATH_TARGET, then
#      run our custom "dblatex" perl script on UserManual.xml, which parses
#      the XML (using the Perl SAX parsers) and dumps a matching LaTeX file
#      to UserManual.tex. This is then regularly processed by pdflatex to
#      generate PDF.
#
#   -- CHM file: again, pre-process the XML files in PATH_TARGET, then use
#      xsltproc to create a .HHP file for the Microsoft Help Compiler, then
#      feed that file to it.
