162 for which the dependencies are available.
163 --disable-interactive Disables the interactive configuration wizard.
164 --distribution-label=[text] Sets a distribution specific version label in
165 the build configuration.
166 --gid=[id|name] Sets the group to run InspIRCd as.
167 --help Show this message and exit.
