Notes:
"not found" means \@param FOO exists in the doxygen documentation,
but the function has no argument FOO. Often this is a
spelling or capitalization error.
"not documented" means a function has an argument FOO,
but the doxygen documentation has no \@param FOO for it.
"unresolved reference" means in "\\ref FOO", FOO doesn't exist in any file
that Doxygen processed. This is expected with "make fast",
but not with "make".
"unrecognized" means this script didn't recognize that line of Doxygen's output.
