.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBclang\fR is a C, \*(C+, and Objective-C compiler which encompasses preprocessing,
parsing, optimization, code generation, assembly, and linking.  Depending on
which high-level mode setting is passed, Clang will stop before doing a full
link.  While Clang is highly integrated, it is important to understand the
stages of compilation, to understand how to invoke it.  These stages are:
.IP "\fBDriver\fR" 4
.IX Item "Driver"
The \fBclang\fR executable is actually a small driver which controls the overall
execution of other tools such as the compiler, assembler and linker.  Typically
you do not need to interact with the driver, but you transparently use it to run
the other tools.
