+    Build design documents.
+
+    For ease of development, couch backend design documents are stored as
+    `.js` files in  subdirectories of
+    `../common/src/leap/soledad/common/ddocs`. This function scans that
+    directory for javascript files, and builds the design documents structure.
+
+    This funciton uses the following conventions to generate design documents:
+
+      - Design documents are represented by directories in the form
+        `<prefix>/<ddoc>`, there prefix is the `src/leap/soledad/common/ddocs`
+        directory.
+      - Design document directories might contain `views`, `lists` and
+        `updates` subdirectories.
+      - Views subdirectories must contain a `map.js` file and may contain a
+        `reduce.js` file.
+      - List and updates subdirectories may contain any number of javascript
+        files (i.e. ending in `.js`) whose names will be mapped to the
+        corresponding list or update function name.
