Using ConTeXts cow font with pdfTeX

I installed them by running

tlmgr install cowfont --repository http://tlcontrib.metatex.org/2012

...which gave me:

tlmgr: package repository http://tlcontrib.metatex.org/2012
[1/1, ??:??/??:??] install: cowfont [656k]
tlmgr: package log updated at d:/programs/texlive/texmf-var/web2c/tlmgr.log

updmap-sys failed (status 1), output:

ERROR:  The following map file(s) couldn't be found:
        koeieletters.map (in d:/programs/texlive/texmf-dist/web2c/updmap.cfg)

        Did you run mktexlsr?

        You can disable non-existent map entries using the option
          --syncwithtrees.

so that package doesn't seem to include the .map file, so I got it from here and after another texhash, re-ran the part that had failed:

updmap-sys --Enable Map koeieletters.map

update: As the package doesn't contain any .sty or .fd files (yet), we have to do the necessary definitions ourselves:

\documentclass{scrartcl}
\usepackage[T1]{fontenc}

\DeclareFontFamily{T1}{CowFont}{}
\DeclareFontShape{T1}{CowFont}{m}{n}{<-> koeieletters}{}

\begin{document}
\usefont{T1}{CowFont}{m}{n}
stop stealing sheep
\end{document}

I tried Nils solution with an TeXLive 2015 installation and I failed:

tlmgr.pl: The TeX Live versions supported by the repository
http://tlcontrib.metatex.org/2012
  (2011--2012)
do not include the version of the local installation
  (2015).

I found no actual repository with cowfont, but I found another solution:

1. Download the source from http://tlcontrib.metatex.org/2012/archive/cowfont.tar.xz
2. Call tlmgr install --file cowfont.tar.xz in the directory of the download.
3. That's it, you can use the font.
4. Repeat the same procedure with http://tlcontrib.metatex.org/2012/archive/cowfont.doc.tar.xz
