+# This GNUmakefile searches the `sources/` directory for files with an extension of `.atom` or `.xml` and applies `transform.xslt` to them, outputting the result in one of the following locations :—
 #
 # • 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).
-# Other files in the corresponding directory (i·e without the `.xml`) are copied over verbatim.
+# Any files in a corresponding sibling directory (i·e without the `.xml`) are copied over verbatim.
 # Only one level of subdirectory is supported.
 #
+# • For files with a location of `sources/*.atom` or `sources/*/*.atom`, the transformed file will be written to `public/%.atom` (where `%` is the filename and subdirectory if applicable).
+#
 # By default, running `make` will do this for all applicable source files.
