+PATH OPTIONS
+
+  --system                      Automatically set up the installation paths

+  --data-dir=[dir]              The location where the data files, such as the
+                                pid file, are stored.

+                                stored.
+                                [$PWD/run/modules]

+EXTRA MODULE OPTIONS
+
+  --enable-extras=[extras]      Enables a comma separated list of extra modules.

+
+MISC OPTIONS
+
+  --clean                       Remove the configuration cache file and start

+  --disable-interactive         Disables the interactive configuration wizard.
+  --help                        Show this message and exit.
+  --uid=[name]                  Sets the user to run InspIRCd as.
+  --socketengine=[name]         Sets the socket engine to be used. Possible
