+[*5] While libextractor is optional, it is recommended to
+     build gnunet against it. If you install it later,
+     you won't benefit from libextractor.
+     If you are a distributor, we recommend to split
+     LE into basis + plugins rather than making LE
+     an option as an afterthought by the user.
+     LE itself is very small, but its dependency chain
+     on first, second, third etc level can be big.
+     There is a small effect on privacy if your LE build
+     differs from one which includes all
+     plugins (plugins are build as shared objects):
+     if users publish a directory with a mixture of file
+     types (for example mpeg, jpeg, png, gif) the
+     configuration of LE could leak which plugins are
+     installed for which filetypes are not providing
+     more details.
+     However, this leak is just a minor concern.
