It's code on my machine; see the attached copy.  Your entry point is
`elinfo-check-directory'.  If you set `elinfo-log-warnings' to a non-nil
value, you should be also able to see some 600 "bugs" where the argument
names differ in code and manual.  So I hope to convince you that fixing
all these is hardly fesible ;-)
