# Hooray! My first little bash script. Look, how ugly it is.
#
# What it does: some HTML postprocessing
#
#   (1) it will extract height information from png images
#       in $doc/manual/$lang/snapshots/
#   (2) it will paste this information into the htmls
#       in $doc/manual/HTML/$lang/
#   (3) it will strip <FIGURE>, <PH> and </FIGURE> tags
#       which aren't legal in HTML 3.2
#   (4) and will strip empty lines
