## \example rmf_xml.py
# This example converts an RMF file to xml, in order to display it in
# an XML viewer such as firefox. Its functionality is largely
# identical to the \c rmf_xml program. The secondary purpose it to
# provide an example of extracting all data from an RMF file and
# converting it to some other source. The data extracted here is
# completely uninterpreted (eg, cartesian coordinates are treated just
# the same as other values). See the source code of rmf_xml for a
# similar example in C++.
