<footnote><para> As a special exception, if the omission of non-free files
would lead to the source failing to build without assistance from the Debian
diff, it might be appropriate to instead edit the files, omitting only the
-non-free parts of them, and/or explain the situation in a README.Debian-source
-<!-- or similarly named -->
+non-free parts of them, and/or explain the situation in a README.source
file in the root of the source tree. But in that case please also urge the
upstream author to make the non-free components easier seperable from the rest
of the source. </para> </footnote>
