The recore_logo_bow postscript file was created using pdftops on the pdf file.

The pdf file was created using OpenOffice draw, by importing the logo eps file
and manually drawing a new bow, based on the eps file (using the imported eps
file didn't work, since it is not transparent). Using the export to pdf function
produced the pdf.

Lastly, the real pdf is onbtained by running ps2pdf on the resulting ps file,
since the OOo generated one contained some stuff that made pdflatex throw
warnings.
