# xmlfilter.sh
# - This script is invoked by the vmchooser tool. It simply filters xml-
# files (taking the path to these files in $1). You might modify it in any
# way to match your needs, e.g. ask some database instead. You can re-
# implement it in any other programming language too. You simply have to
# return a list of proper xml files to be interpreted by the vmchooser
# binary). Please check for vmchooser.sh too ...
