 # • For files with a location of `sources/index.xml` or `sources/index-*.xml`, the transformed file will be written to `public/%.html` (where `%` is the filename).
 #
 # • For all other files with a location of `sources/*.xml` or `sources/*/*.xml`, the transformed file will be written to `public/%/index.html` (where `%` is the filename and subdirectory if applicable).

 # • For files with a location of `sources/index.xml` or `sources/index-*.xml`, the transformed file will be written to `public/%.html` (where `%` is the filename).
 #
 # • For all other files with a location of `sources/*.xml` or `sources/*/*.xml`, the transformed file will be written to `public/%/index.html` (where `%` is the filename and subdirectory if applicable).

+# Any files in a corresponding sibling directory (i·e without the `.xml`) are copied over verbatim.

 # Only one level of subdirectory is supported.
