-These are the test suite requirements:
+About libextractor being optional:
+@example
+While libextractor ("LE") 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.
