# All arguments must be paths to the source XML files for a package. The
# output will be of the form:
#
# file.xml: /absolute/import/path
#
# Relative paths will be concatenated with the directory name of the source
# file. Parent references are resolved by replacing "/foo/../bar" with
# "/bar". Absolute imports are taken as-is.
#
# Namespace prefixes are ignored and the first attribute to the `import'
# node must be `@package', and must appear on the same line.
