If you have access to the current r-devel snapshot, use R CMD check from
there (in fact, I think you could simply use codoc() from there).  The
newer versions report which file caused the problem, etc.  If you do not
have such access, use codoc() from the R prompt with `keep = TRUE', and
inspect the tempfiles.  Typically, the problems come from statements in
\usage which are not valid R code.
