// A framework that lets you run jobs under a BOINC client
// without a project, and without fake XML files
// This lets you debug client/app interactions.
//
// To use this framework:
// - edit this file to describe your application:
//      input/output files, attributes, etc.
//      NOTE: currently it's set up for an app that uses the WSL wrapper
//
// - build the BOINC client with these changes
// - make a BOINC data directory, say 'test'
//      (or you can use an existing BOINC data directory,
//      in which case the client will also run jobs that are there)
// - make a directory test/slots/app_test
//      The client will run the test job there.
//      Clean it out between runs.
// - make a dir test/projects/app_test
// - In the project directory, put:
//      - the executable file
//      - the input file(s) with physical names
// - run boinc (in the data directory if you created one)
//      when the job is done, the client won't clean out the slot dir.
//      You can examine the contents of the slot dir,
//      and examine the output files in the project dir.
//      Clean out the slot dir between tests.
