 installing [pathogen.vim](https://github.com/tpope/vim-pathogen), and

-## FAQ
+### FAQ
 
 > Why does it take so long for Vim to startup?
 
-That's either [classpath.vim][] or [salve.vim][].
+The short answer is because the JVM is slow.
+
+The first time you load a Clojure file from any given project, foreplay.vim
+sets about trying to determine your class path, leveraging either
+`lein classpath` or `mvn dependency:build-classpath`.  This takes a couple of
+seconds or so in the best case scenario, and potentially much longer if it
+decides to hit the network.  (I don't understand why "tell me the class path"
+requires hitting the network, but what do I know?)
+
+Because the class path is oh-so-expensive to retrieve, foreplay.vim caches it
+in `g:CLASSPATH_CACHE`.  By default, this disappears when you exit Vim, but
+you can save it across sessions in `.viminfo` with this handy option:
+
+    set viminfo+=!
+
+The cache is expired when the timestamp on `project.clj` or `pom.xml` changes.

-*fireplace.txt*  Clojure REPL support
-
-Author:  Tim Pope <http://tpo.pe/>
-License: Same terms as Vim itself (see |license|)
-
-This plugin is only available if 'compatible' is not set.
-
-                                                *fireplace*
-While not strictly necessary, this plugin works best with the middleware
-provided by <https://github.com/clojure-emacs/cider-nrepl>.
-
-CONNECTING TO A REPL                            *fireplace-connect*
-
-Connecting to lein repl happens automatically.  If you have a different setup,
-you can connect by hand.
-
-                                                *fireplace-:Connect*
-:Connect {proto}://{host}:{port} {path}
-                        Connect to a REPL server.  The path is the root of the
-                        project that the REPL applies to.
-
-:Connect                Interactively prompt for the options to connect to a
-                        REPL server.
-
-The REPL is used for the commands below. If no REPL is found for the current
-buffer and 'path' contains at least one jar file, java (or $JAVA_CMD) is
-invoked directly, which can be quite slow depending on your setup.
-
-The only adapter shipped with fireplace.vim is for nREPL.  You need either
-|if_pyth| or the python command in your PATH.
-
-                        *fireplace-piggieback* *fireplace-clojurescript*
-ClojureScript can be evaled with Piggieback if the appropriate nREPL
-middleware is loaded: https://github.com/cemerick/piggieback.  Be aware that
-your ClojureScript files must be available on the classpath for this to work
-properly, and that not all operations are supported.
-
-                                                *fireplace-:Piggieback*
-:Piggieback [{env}]     Create a new nREPL session and invoke

-                        default (Rhino) environment.  This will also happen
-                        automatically on first eval in a ClojureScript buffer
-                        if not invoked explicitly. If {env} is a number, the
-                        piggieback repl-env will will use a cljs.repl.browser
-                        (rather than a Rhino) env with the port set to the
-                        number provided.

+*foreplay.txt*  Clojure REPL tease
+
+Author:  Tim Pope <http://tpo.pe/>
+License: Same terms as Vim itself (see |license|)
+
+This plugin is only available if 'compatible' is not set.
+
+You need Clojure runtime files to use this plugin.  Try VimClojure.  You don't
+need the interactive stuff.
+
+CLASSPATH                                       *foreplay-classpath*
+
+Upon loading a Clojure buffer, the 'path' option is automatically set to your
+class path.  The class path is found by `lein classpath`, `mvn
+dependency:build-classpath`, or failing both of those, $CLASSPATH.
+
+Finding the class path can be slow.  To cache it across multiple invocations
+of Vim, try
+
+    set viminfo+=!
+
+LEININGEN                                       *foreplay-leiningen*
+
+Leiningen support is currently bare bones.  If a Leiningen project is found,
+'makeprg' will be set to "lein".
+
+Leiningen 2.x writes to target/repl-port when `lein repl` is invoked.  If this
+file is found, an nREPL connection will be established automatically.
+
+CONNECTING TO A REPL                            *foreplay-connect*
+
+                                                *foreplay-:Connect*
+:Connect {proto}://{host}:{port}
+                        Connect to a REPL server.
+
+:Connect                Interactively prompt for the options to connect to a
+                        REPL server.
+
+The REPL is used for the commands below. If no REPL is found for the current
+buffer, java (or $JAVA_CMD) is invoked directly (using 'path' as the class
+path), which can be quite slow depending on your setup.
+
+The only adapter shipped with foreplay.vim is for nREPL.  You need Ruby
+installed and either |if_ruby| or the ruby command in your PATH.
+
+DOCUMENTATION                                   *foreplay-documentation*
+
+                                                *foreplay-:Doc*
+:Doc {symbol}           Show the docs for the given symbol.
+
+                                                *foreplay-:Javadoc*
+:Javadoc {class}        Open the java docs for the given class in a browser.
+
+                                                *foreplay-K*
+K                       Look up docs for keyword under cursor.
+
+                                                *foreplay-:FindDoc*
+:FindDoc {arg}          Wrapper around (clojure.repl/find-doc ...).
+
+                                                *foreplay-:Apropos*
+:Apropos {arg}          Wrapper around (clojure.repl/apropos ...).
+
+                                                *foreplay-:Source*
+:Source {symbol}        Show the source for the given symbol.
+
+                                                *foreplay-[d*
+[d                      Show source for keyword under cursor.
+]d
+
+NAVIGATING                                      *foreplay-navigating*
+
+These commands will never use a remote REPL, only a local one, as file paths
+on a remote server wouldn't be very useful locally.
+
+                                                *foreplay-[_CTRL-D*
+[<C-D>                  Jump to the source of the keyword under the cursor.
+]<C-D>
+
+                                                *foreplay-CTRL-W_CTRL-D*
+<C-W><C-D>              Jump to the source of the keyword under the cursor in
+<C-W>d                  a split.
+
+                                                *foreplay-gf*
+gf                      Go to the file for the namespace under the cursor.

+:Djump {symbol}         Jump to the definition for the given symbol.
+
+                                                *foreplay-:Dsplit*
+:Dsplit {symbol}        Jump to the definition for the given symbol in a
+                        split.
+
+EVALUATING CODE                                 *foreplay-eval*
+
+All code is evaluated in the namespace of the current file, requiring it if
+necessary.  If the current file sits outside the class path (project.clj, for
+example), the user namespace is used instead.
+
+                                                *foreplay-:Require*
