+is a new protocol being devloped by several members of
+gopherspace. It aims to solve some of the long-standing technical
+issues associated with gopher as a protocol, while keeping the major benifits.
+For instance, it _requires_ encrypted connections, it does away with
+the selector type, and allows servers to explicitly specify the
+character coding scheme used for text documents.
+
+The latest versions of Elpher aim to provide seemless navigation between
+gemini and gopher documents. Basically you should be able to open,
+bookmark, download and otherwise interact with gemini pages in exactly
+the same way as you do with other non-gemini pages. The only major
+difference from your perspective as a user is that you should no longer
+have to worry about manually toggling TLS on or off (for gemini it's
+always on), and you should never have to manually set a character coding
+scheme.
+
+I should emphasize however that, while it is definitely functional,
+Elpher's gemini support is still experimental, and various aspects will
+change as the protocol develops further. Additionally, the use of
+client TLS certicificates is not yet supported.

@chapter Customization
Various parts of Elpher can be customized via the
the appearance of Elpher, including one face per menu item type.
The group also contains variables for customizing the behaviour of
-Elpher. This includes how to open arbitrary (non-gopher) URLs,
-whether to display buffer headers, whether to look for naked URLs in
-gopher menus (as opposed to just plain text files), and whether
-to prompt for confirmation when switching away from TLS.
