  Since release 15.09 there is a new TeX Live packaging that lives entirely
  under attribute <varname>texlive</varname>.

     For basic usage just pull <varname>texlive.combined.scheme-basic</varname>

     It typically won't work to use separately installed packages together.
     Instead, you can build a custom set of packages like this:
<programlisting>
texlive.combine {
  inherit (texlive) scheme-small collection-langkorean algorithms cm-super;
}
      </programlisting>
     There are all the schemes, collections and a few thousand packages, as
     defined upstream (perhaps with tiny differences).
    </para>
   </listitem>
   <listitem>
    <para>
     By default you only get executables and files needed during runtime, and a
     little documentation for the core packages. To change that, you need to
     add <varname>pkgFilter</varname> function to <varname>combine</varname>.
<programlisting>
texlive.combine {
  # inherit (texlive) whatever-you-want;
  pkgFilter = pkg:
    pkg.tlType == "run" || pkg.tlType == "bin" || pkg.pname == "cm-super";
  # elem tlType [ "run" "bin" "doc" "source" ]
  # there are also other attributes: version, name
}
      </programlisting>
    </para>
   </listitem>
   <listitem>
    <para>
     You can list packages e.g. by <command>nix-repl</command>.
<programlisting>
$ nix-repl
nix-repl> :l &lt;nixpkgs>
nix-repl> texlive.collection-&lt;TAB>
      </programlisting>
    </para>
   </listitem>
   <listitem>
    <para>
     Note that the wrapper assumes that the result has a chance to be useful.
     For example, the core executables should be present, as well as some core
     data files. The supported way of ensuring this is by including some
     scheme, for example <varname>scheme-basic</varname>, into the combination.
