[racket] code metrics

Anyone know of a good tool to measure racket code?

Some measurements I'd like are:
 - Total source lines of code
 - Total unique source lines of code
 - Number of modules
 - Number of functions
 - Number of tests
 - Test coverage
 - Average number of lines per module
 - Maximum number of lines per module
 - Average number of lines per function
 - Maximum number of lines per function

etc.

If it was smart enough to identify duplicate function definitions (from
different modules), unneeded requires, and unused provides, that would be extra
awesome : )

Thanks,
Jordan
