# Generate node tree from verbose logfile
#
# HOWTO USE
# =========
#
# First of all, you need to recompile modules slideshow and canvas
# with VERBOSE=t set in the environment, and debug=t defined at the
# build tool command line. Then run your slideshow and redirect stdout
# to a file.
#
# Then, call 'nodetree.sh trace-file > tree.ps' to generate a
# PostScript file for the AnimationNode tree generated during the show.
# Since these easily get pretty huge, use only one page, and try to
# limit the slide content (which have effects assigned, that is) to
# the bare minimum (to reproduce your bug, or whatever you need this
# for).
#
# The generated output will have all nodes color-coded with their state
# at the point when the tree was dumped (see colors.sh for the color
# codes)
#
# When looking for the mechanics that generate the relevant output,
# grep for the DEBUG_NODES_SHOWTREE macros in the slideshow source:
# Each such place dumps the current node tree to the trace output. Thus,
# if you need to check the tree state at other places or times, just add
# a DEBUG_NODES_SHOWTREE
