-cause the builtin help to render incorrectly. Version 1.2.14 is known
-to have this problem.
+Fish is developed using GCC, with the goal of using only C89 language
+features. Fish does, however use the *wprintf family of functions,
+which are new to the C99 standrard. It is not unlikely that any given
+release contains a few GCC:isms, but ICC 9.0.030 has been found to
+produce working binaries. GCC 2.95.* won't compile fish, but GCC 3.2.3
+is known to work. Patches to fix any remaining GNU:isms are welcome.
 
-In version 1.9.2, the installation prefix for fish rpms and debs has
-changed from /usr/local to /usr. The package should automatically
-change any instances of /usr/local/bin/fish in /etc/passwd to
-/usr/bin/fish, but some programs, like screen, may need to be
-restarted to notice the changes.  You may also run into problems when
-switching between using a package and personal builds.

 The universal variable server. fishd is automatically started by fish
 if a fishd server isn't already running. fishd reads any saved
-variables from ~/.fishd, and takes care of commonication between fish
+variables from ~/.fishd, and takes care of communication between fish
 instances. When no clients are running, fishd will automatically shut
 down and save.
 
+\subsection fishd-commands Commands
+
+Fishd works by sending and receiving commands. Each command is ended
+with a newline. These are the commands supported by fishd:
+
+<pre>set KEY:VALUE
+set_export KEY:VALUE
+</pre>
+
+These commands update the value of a variable. The only difference
+between the two is that <tt>set_export</tt>-variables should be
+exported to children of the process using them. The variable value may
+be escaped using C-style backslash escapes. In fact, this is required
+for newline characters, which would otherwise be interpreted as end of
+command.
+
+<pre>erase KEY
+</pre>
+
+Erase the variable with the specified name.
+
+<pre>barrier
+barrier_reply
+</pre>
+
+A \c barrier command will result in a barrier_reply being added to
+the end of the senders queue of unsent messages. These commands are
+used to synchronize clients, since once the reply for a barrier
+message returns, the sender can know that any updates available at the
+time the original barrier request was sent have been received.
