This section is unclear and needs to be cleaned up. In particular, the last
paragraph -- earlier in the node already advises that require statement, so we
probably shouldn't repeat it here. Is the point of this section to
differentiate project page from day page? If so, it needs to be rewritten to
focus on that.

`planner-timeclock-summary-proj.el' produces task / time breakdowns
on plan pages. Reports are of the form:

TASK 0 | duration
TASK 1 | duration
TOTAL | duration.

To use, add `(require 'planner-timeclock-summary)' to your
`~/.emacs'. Call `planner-timeclock-summary-proj-current' from a
project page. The report is inserted at the current position in the
buffer. The function `planner-timeclock-summary-proj-section' does the
same but the report is inserted inside a section called `* Report'.
