+# This function determines whether a .changes file is source-only from
+# the point of view of dak. Thus, it permits *_source.buildinfo
+# files.
+#
+# It does not, however, permit any other buildinfo files. After a
+# source-only upload, the buildds will try to upload files like
+# foo_1.2.3_amd64.buildinfo. If the package maintainer included files
+# named like this in their (otherwise) source-only upload, the uploads
+# of the buildd can be rejected by dak. Fixing the resultant
+# situation can require manual intervention. So we block such
+# .buildinfo files when the user tells us to perform a source-only
+# upload (such as when using the push-source subcommand with the -C
+# option, which calls this function).
+#
+# Note, though, that when dgit is told to prepare a source-only
+# upload, such as when subcommands like build-source and push-source
+# without -C are used, dgit has a more restrictive notion of
+# source-only .changes than dak: such uploads will never include
+# *_source.buildinfo files. This is because there is no use for such
+# files when using a tool like dgit to produce the source package, as
+# dgit ensures the source is identical to git HEAD.
