--- __An important note.__ Currently, package /resolv/ at
--- [hackage.org](https://hackage.haskell.org/package/resolv) has
--- [a bug](https://github.com/haskell-hvr/resolv/pull/12) which leads to
--- memory leaks on every DNS query. This makes service /collectUpstreams/ 
--- from module /NgxExport.Tools.Resolve/ leak as well, because it makes DNS
--- queries regularly. To prevent memory leaks, you can clone /resolv/ from
--- [this fork](https://github.com/lyokha/resolv) and /v1-install/ it from
--- the source. Or, if you prefer /v2-build/, simply put lines
