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. Requires
-that you have I<dot> and I<gv> programs installed. Hidden option,
-useful for debugging.
+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 the Graphviz format. Hidden
-option, useful for debugging.
+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. Hidden option, useful for debugging.
+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>
-=item B<--help>
+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.
+
+=item B<-help>
Print a summary of command-line options and exit.
-=item B<--help-hidden>
+=item B<-help-hidden>
Print a summary of command-line options and exit. Print help even for
options intended for developers.
Print version information and exit.
+=item B<@>I<file>
+
+Read command-line options from I<file>. The options read are inserted
+in place of the original @I<file> option. If I<file> does not exist, or
+cannot be read, then the option will be treated literally, and not
+removed.
+
+Options in I<file> are separated by whitespace. A whitespace character
+may be included in an option by surrounding the entire option in
+either single or double quotes. Any character (including a backslash)
+may be included by prefixing the character to be included with a
+backslash. The file may itself contain additional @I<file> options;
+any such options will be processed recursively.

By default, LLVMC is built with some standard configuration libraries
=item B<-opt>
-Enable optimization with B<opt>.
+Enable optimization passes with B<opt>. To pass options to the B<opt> program

-Add a directory to the header file search path. This option can be
-repeated.
+Add a directory to the header file search path.

+
+=item B<-F> I<directory>

+Add I<directory> to the framework search path.
=item B<-l>I<name>
Link in the library libI<name>.[bc | a | so]. This library should
be a bitcode library.

+be a bitcode library.
+
=item B<-emit-llvm>
-Make the output be LLVM bitcode (with B<-c>) or assembly (with B<-S>) instead
-of native object (or assembly). If B<-emit-llvm> is given without either B<-c>
-or B<-S> it has no effect.
