Comment (by nickm):

 > How can I discover the modules (or files) that are only used by a
 particular set of modules, and no other modules?

 I usually use shell pipelines for this.  For example, to find all the
 headers that are included from dirauth, I would do:

 {{{
 git grep '#include "' src/feature/dirauth/ | awk '{print $2}' |sort  |uniq
 > HEADERS
 }}}

 Then to find out which ones are not used elsewhere, I would do something
 like
 {{{
 for h in $(cat headers); do
   printf "$h "; git grep -l "#include $h" |grep -v feature/dirauth |grep
 -v src/test | wc -l
 done |sort -n -k2
 }}}

 That could probably be cleaner, but you get the idea. We can and should
 make scripts for this once we have more experience with exactly which
 tests are useful.
