-#+TITLE: Simple Server that accepts survey answers
-
-Run with:
-#+BEGIN_SRC
-guile server.scm
-#+END_SRC
-
-Will listen to localhost:8080, and accept files sent via POST with
-mimetypes of either ~text/plain~ (which will be appended to a single
-file in the working directory) or ~text/age~ (which will be kept as a
-single file).
-
-Expects a custom header ~X-Survey~ in these requests to know which survey
-the answer belongs to.
