+"""Dromaeo benchmark automation script.
+
+Script runs dromaeo tests in browsers specified by --browser switch and saves
+results to a spreadsheet on docs.google.com.
+
+Prerequisites:
+1. Install Google Data APIs Python Client Library from
+   http://code.google.com/p/gdata-python-client.
+2. Checkout Dromaeo benchmark from
+   http://src.chromium.org/svn/trunk/src/chrome/test/data/dromaeo and provide
+   local path to it in --dromaeo_home switch.
+3. Create a spreadsheet at http://docs.google.com and specify it's name in
+   --spreadsheet switch
+
+Benchmark results are presented in the following format:
+browser | date time
+test 1 name|m11|...|m1n|test 1 average mean| |e11|...|e1n|test 1 average error
+test 2 name|m21|...|m2n|test 2 average mean| |e21|...|e2n|test 2 average error
+...
+
+Here mij is mean run/s in individual dromaeo test i during benchmark run j,
+eij is error in individual dromaeo test i during benchmark run j.
+
+Example usage:
+dromaeo_benchmark_runner.py -b "E:\chromium\src\chrome\Release\chrome.exe"
+    -b "C:\Program Files (x86)\Safari\safari.exe"
+    -b "C:\Program Files (x86)\Opera 10.50 pre-alpha\opera.exe" -n 1
+    -d "E:\chromium\src\chrome\test\data\dromaeo" -f dom -e example@gmail.com
