116 <|BOLD --portable|> Automatically set up the installation paths for
117 portable installation.
118 <|BOLD --system|> Automatically set up the installation paths for

161 for which the dependencies are available.
162 <|BOLD --disable-interactive|> Disables the interactive configuration wizard.
163 <|BOLD --distribution-label <TEXT>|> Sets a distribution specific version label in
164 the build configuration.
165 <|BOLD --gid <ID|NAME>|> Sets the group to run InspIRCd as.
166 <|BOLD --help|> Show this message and exit.
167 <|BOLD --socketengine <NAME>|> Sets the socket engine to be used. Possible
169 <|BOLD --uid [ID|NAME]|> Sets the user to run InspIRCd as.
170 <|BOLD --update|> Updates the build environment with the settings
175 <|BOLD CXX=<NAME>|> Sets the C++ compiler to use when building the
