# This script is designed to convert the pprof output from
# APD (http://pecl.php.net/apd/) to one readable by tdecachegrind. To use
# this script:
#
# 1) Install APD.
# 2) Profile your script with APD accordingto the directions in it's
# README file.
# 3) Take the pprof trace file for your script (pprof.XXXXX.Y) and run it
# through this script as follows:
# > pprof2calltree -f pprof.12345.1
# This creates a new file cachegrind.out.12345.1
# 4) View your trace with pprof2calltree cachegrind.out.12345.1
