 #	Will take action against each distribution in turn
 #	-d is a necessary destination directory for the perl mods
 #	If -c is set, will remove the module build directories and exit
+# If -e is set, will extract module
 #	If -m is set, will run perl Makefile.PL and make
 #	If -t is set, will run make test
 #	If -i is set, will run make install
+# If -s <section> specified will only work on that section in the

 #	Options are discrete. This is because an overall ./configure, make, make test, make install
 #	are run in different invocations. Obviously, you can't run a -t without a -m, but there's no
