+= PyBOINC: simplified BOINC application development in Python (design doc) =
+
+This is a proposed design for making developing
+BOINC applications as simple as possible.
+PyBOINC provides a master/slave model:
+the master runs on the server, and the slave is distributed.
+
+Here's an example, which sums the squares of integers from 1 to 100.
+The application consists of three files.
+The first, '''app_types.py''', defines the input and output types:
+{{{
+class Input:
+    def __init__(self, arg):
+        self.value = arg
+
+class Output:
+    def __init__(self, arg):
+        self.value = arg;
+}}}
+
+The second file, '''app_master.py''', is the master program:
+{{{
+import app_types
+
+def make_calls():
+    for i in range(100):
+       input = Input(i);
+       pyboinc_call('app_slave.py', input)
+
+def handle_result(output):
+    sum += output.value
+
+sum = 0
+
+pyboinc_master(make_calls, handle_result)
+
+print "The answer is %d", sum
+}}}
+
+The third file, '''pyboinc_slave.py''', is the slave function:
+
+{{{
+import app_types
+
+input = pyboinc_get_input()
+output = Output(input.value*input.value);
+pyboinc_return_output(output);
+}}}
