#  Makefile for building SAMP document.
#  Main useful targets are
#
#     build:    builds PDF and HTML documents, as well as SAMP.zip file
#               suitable for submission to IVOA doc coordinator
#               (default target)
#     clean:    deletes all files not under version control

#  Requirements:
#     XML validator and XSLT processor
#     pdflatex
#     PDF->GIF converter (ImageMagick)
#     jar (JDK)
#  All most likely present on, e.g., a linux disribution.
#  Could use substitites for some of these if they are not available.
