types of transactions.  This should be fixed.

   A successful student on this task will:

      * Write various test cases for Ledger-CLI that will clearly show the

        floating point issue.

      * Rework the codebase to use fixed-point arithmetic so those bugs are

        closed.

      * Shepherd the patch upstream.

      * Close any bug tickets in the bug tracker that relate to this issue.

      * Time permitting: verify that other Ledger implementations don't

        face the same problem.

   Note that because this would be a major "bombing run" sort of change,

   there may be some resistance to upstreaming this patch, so this task may

   be harder than it looks on the surface from a community advocacy angle.  

3. Build a better test suite for [Ledger-CLI](http://www.ledger-cli.org/).

   Since this project relies so heavily on Ledger-CLI, we'd really like there

   to be a full test coverage for Ledger-CLI.  To do that, a student will

   need to be already somewhat familiar C++ and willing to learn about how to

   set up test suites for C++ programs, and likes writing tests.  The student

   could easily spend the whole summer just writing tests and not finish.

    Ledger-CLI does have a basic test suite, but it might turn out that using

    a more "full featured" test harness is useful.  The student will

    investigate and discuss this possibility with the mentor.  It would also

    be nice if lcov or other test-coverage tool could generate reports

    automatically.

    While this project is of primary interest to this project, it will

    require careful coordination with Ledger-CLI as an upstream, and we'll

    help mentor the student in that.

4. Build a better Python interface to Ledger-CLI for use by our API.

   Right now, Ledger-CLI has a rather incomplete Python interface, based on

   [Boost.Python](http://www.boost.org/doc/libs/1_55_0/libs/python/doc/).

   However, the right approach is probably to use

   [SWIG](http://www.swig.org/) or some other similar mechanism to build a

   proper Python API.  Perhaps Ledger-CLI could stick with Boost.Python, but

   what's there clearly needs an overhaul.  The upside of using SWIG will be

   that we can get APIs for other languages too. 

   While this project is of primary interest to this project, it will require

   careful coordination with Ledger-CLI as an upstream, and we'll help mentor

   the student in that.
