+There are special cases where creation of the package comes from many

+
+Consider the `flymake-perlcritic` recipe,
+
+```elisp
+(flymake-perlcritic :repo "illusori/emacs-flymake-perlcritic"
+                    :fetcher github
+                    :files ("*.el" ("bin" "bin/flymake_perlcritic")))
+```
+
+which will result in a package structure of,
+
+```
+flymake-perlcritic-YYYMMDD
+|-- bin
+|   `-- flymake_perlcritic
+|-- flymake-perlcritic-pkg.el
+`-- flymake-perlcritic.el
+```
+
+Notice that specifying an entry in `:files` that is a list takes the
+first element to be the destination directory.  These can be embedded
+further, such as the following---hypothetical---entry for `:files`,
+
+```elisp
+("*.el" ("snippets" 
+         ("html-mode" "snippets/html-mode/*")
+         ("python-mode" "snippets/python-mode/*")))
+```
+
+which would result in a package with `*.el` in something like,
+
+```
+package-YYYYMMDD
+|-- snippets
+|   |-- html-mode
+|   |   |-- div
+|   |   `-- html
+|   `-- python-mode
+|       |-- for
+|       `-- main
+`-- package.el
+```
+
+But a better solution, given that we probably want to copy the
+*entire* `snippets` directory to the root of the package, we could
+just specify that directory.  Consider the `pony-mode` recipe,
+
+```elisp
+(pony-mode
+ :repo "davidmiller/pony-mode"
+ :fetcher github
+ :files ("src/*.el" "snippets"))
+```
+
+which generates the package,
+
+```
+pony-mode-YYYYMMDD
+|-- pony-mode-pkg.el
+|-- pony-mode.el
+|-- pony-tpl.el
+`-- snippets
+    |-- html-mode
+    |   |-- bl
