+be found.])
+ (p [In order to actually put web pages for each issue at the
+aforementioned HTTP URIs, we need the ,(code "#:web-files") keyword
+argument. The ,(code "#:web-files") keyword argument takes a list of
+,(code "<file>") objects that describe files on the website. Each file
+object constitutes a file path and something we call a ,(emph "writer
+function"). A writer function is a one-argument function that accepts
+a port and writes the contents of a file to it. Here, we use the
