# This script is a bunch of utilities for computing statistics about the textruns
|
|
# created during a Gecko run.
|
|
#
|
|
# Usage:
|
|
# 1) Uncomment #define DUMP_TEXT_RUNS in gfxAtsuiFonts.cpp
|
|
# 2) Build
|
|
# 3) Run over some test set, redirecting stdout to a file
|
|
# 4) Pipe that file through this script
|
|
|

# spaces
