# takes a bbbike[1] streetfile as input and converts it to some osm xml file format.
#
# bbbike files are usually not in polar coordinate format, you will have to convert them first, e.g.
# like this (from within your local bbbike checkout):
#
#  perl ./miscsrc/convert_coordsys standard polar < data/strassen > /tmp/strassen.polar
#
#  [1]:	bbbike is the free Berlin bike map system: http://bbbike.sourceforge.net/
#  		use the cvs download from sourceforge to retrieve the scripts and data.
