This is the program 'autotool' for automatic grading 
of student homework in (theoretical) computer science.


source code package structure (on branch classic-via-rpc)
(cf. http://dfa.imn.htwk-leipzig.de/bugzilla/show_bug.cgi?id=305 )

tool/interface: 
defines the programmatic API (Challenger.Partial) for task types.

tool/collection: (depends on interface)
contains implementation of task types, so that is where the "semantics" sits,
and it is a huge package (> 700 modules).

tool/db: (depends on interface and collection)
the "classical" autotool: database of student and task data, and a web
frontend.
Everything in one big executable (autotool-super.cgi)

tool/test: (depends on interface, collection, db)
extract test cases (task instances, student solutions, autotool answers) from
the data base and file system, recomputes the results, and generates reports.

tool/server-interface: (depends on interface)

tool/server-implementation: (depends on collection)
XML-RPC server built during the autolat project. this is a stateless server
(just the semantics, no database)

tool/client: (no dependencies)
client that accesses a remote XML-RPC-server. the client is stateless as well,
not database, no user data. It just exemplifies how to call the server methods.
