+=head1 NAME
+
+llvmgcc - LLVM C front-end
+
+=head1 SYNOPSIS
+
+llvmgcc [options] filename
+
+=head1 DESCRIPTION
+
+The B<llvmgcc> command is the LLVM C front end.  It is a modified
+version of gcc that takes C programs and compiles them into LLVM
+bytecode or assembly language, depending upon the options.
+
+Unless the B<-S> option is specified, B<llvmgcc> will use the
+L<gccas|gccas> program to perform some optimizations and create an
+LLVM bytecode file. Unless the B<-c> option is specified, B<llvmgcc>
+will also use the L<gccld|gccld> program to perform further
+optimizations and link the resulting bytecode file(s) with support
+libraries to create an executable program.
+
+Being derived from the GNU Compiler Collection, B<llvmgcc> has many
+of gcc's features and accepts most of gcc's options.  It handles a
+number of gcc's extensions to the C programming language.
