# This script generate metrics html pages for either compile times or
# footprint.
#
# Compile times:
# Parse the build.txt file from an autobuild that was generated with the
# g++_metric.sh script, e.g., with CXX=g++_metric.sh which outputs
# compile times on a per object basis, and use the data to generate time
# series graphs with gnuplot.
#
# Footprint:
# Parse the build.txt file and and the *.map files, generated with LDFLAGS
# set to =-Xlinker -M -Xlinker -Map -Xlinker \$@.map and static_libs_only=1.
#
# For use with an autobuild, place a line something like this in the xml file,
# after the log file is closed, but before it's moved.
#
#  <command name="shell"  options="$ACE_ROOT/bin/generate_compile_stats.sh <path>/build.txt <destination> Footprint" />
