   3 # 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 :—
   4 #
   5 # • 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).
   6 #
   7 # • 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).
   8 # Any files in a corresponding sibling directory (i·e without the `.xml`) are copied over verbatim.
   9 # Only one level of subdirectory is supported.
  10 #
  11 # • 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).
  12 #
  13 # By default, running `make` will do this for all applicable source files.

  53 #
  54 # • Saves the output to `$(2)`.
