+=item B<-o> I<filename>
+
+Output file name.
+
+=item B<-x> I<language>
+
+Specify the language of the following input files until the next B<-x>
+option.
+
+=item B<-load> I<plugin_name>
+
+Load the specified plugin DLL. Example:
+S<-load $LLVM_DIR/Release/lib/LLVMCSimple.so>.
+
+=item B<-v> or B<--verbose>
+
+Enable verbose mode, i.e. print out all executed commands.
+
+=item B<--check-graph>
+
+Check the compilation for common errors like mismatched output/input language
+names, multiple default edges and cycles. Because of plugins, these checks can't
+be performed at compile-time. Exit with code zero if no errors were found, and
+return the number of found errors otherwise. Hidden option, useful for debugging
+LLVMC plugins.
+
+=item B<--view-graph>
+
+Show a graphical representation of the compilation graph and exit. Requires that
+you have I<dot> and I<gv> programs installed. Hidden option, useful for
+debugging LLVMC plugins.
+
+=item B<--write-graph>
+
+Write a I<compilation-graph.dot> file in the current directory with the
+compilation graph description in Graphviz format (identical to the file used by
+the B<--view-graph> option). The B<-o> option can be used to set the output file
+name. Hidden option, useful for debugging LLVMC plugins.
+
+=item B<--save-temps>
+
+Write temporary files to the current directory and do not delete them on
+exit. This option can also take an argument: the I<--save-temps=obj> switch will
+write files into the directory specified with the I<-o> option. The
+I<--save-temps=cwd> and I<--save-temps> switches are both synonyms for the
+default behaviour.
+
+=item B<--temp-dir> I<directory>
+
+Store temporary files in the given directory. This directory is deleted on exit
+unless I<--save-temps> is specified. If I<--save-temps=obj> is also specified,
+I<--temp-dir> is given the precedence.
