The executables can still be static, that's just a detail.  By having a
defined line between the user tools, and the backend library, you can help
keep code where it belongs.  Most of the user programs have a mix of
interface code, and what should belong in a library.  It should help cut
down on code duplication.

A tool like doxygen uses the comments in the code to generate the API docs.
It makes you format your comments in a certain manner, but that's not a bad
thing since it keep comments similar (easier to read).  Take a look if you
have time: http://www.doxygen.org.
