# Generates debian/control from debian/control.in by appending a uuencoded
# string representing a png icon named after a package defined in
# debian/control.in and located under debian/package-icons.
#
# For example, if debian/control.in defines a package called "foo" and a png
# named "foo.png" is found under debian/package-icons, then "foo.png" is assumed
# to be of the prescribed size of 26x26 pixels, and will be added as a
# "XB-Maemo-Icon-26: <uuencoded icon file contents>" tag to the generated
# "debian/control" file.
