+catlfish(1) -- Certificate Transparency log node
+================================================
+
+## SYNOPSIS
+
+`catlfish` [`-c` <config-name>] <command>
+
+## DESCRIPTION
+
+`catlfish` is a Certificate Transparency log. A node in a log instance
+can be started using the `start-node` command and stopped using the
+`stop-node` command.
+
+<command> is one of:
+
+* `start-node` [`-a` <application>]:
+  Start a `catlfish` node.
+
+* `stop-node`:
+  Stop a `catlfish` node.
+
+## OPTIONS
+
+* `-a` <application>:
+  Use <application> as the `-boot` argument to erl(1) instead of the
+  default application `catlfish`.
+
+* `-c` <config-name>:
+  Use <config-name> to find the configuration file for the node
+  instead of the name of the basename of the current working
+  directory. The configuration file should be generated by
+  genconfig(1).
+
+* `-d` <directory>:
+  Use <directory> as the `pipe_dir` argument to run_erl(1) instead of
+  using the current working directory (`.`).
+
+* `-l` <directory>:
+  Use <directory> as the `log_dir` argument to run_erl(1) instead of
+  using `./log'.
