+# 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
