+llvm-config - Print LLVM compilation options
+============================================
+
+
+SYNOPSIS
+--------
+
+
+**llvm-config** *option* [*components*...]
+
+
+DESCRIPTION
+-----------
+
+
+**llvm-config** makes it easier to build applications that use LLVM.  It can
+print the compiler flags, linker flags and object libraries needed to link
+against LLVM.
+
+
+EXAMPLES
+--------
+
+
+To link against the JIT:
+
+
+.. code-block:: perl
+
+   g++ `llvm-config --cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp
+   g++ `llvm-config --ldflags` -o HowToUseJIT HowToUseJIT.o \
+       `llvm-config --libs engine bcreader scalaropts`
+
+
+
+OPTIONS
+-------
+
+
+
+**--version**
+
+ Print the version number of LLVM.
+
+
+
+**-help**
+
+ Print a summary of **llvm-config** arguments.
+
+
+
+**--prefix**
+
+ Print the installation prefix for LLVM.
+
+
+
+**--src-root**
+
+ Print the source root from which LLVM was built.
+
+
+
+**--obj-root**
+
+ Print the object root used to build LLVM.
+
+
+
+**--bindir**
+
+ Print the installation directory for LLVM binaries.
+
+
+
+**--includedir**
+
+ Print the installation directory for LLVM headers.
+
+
+
+**--libdir**
+
+ Print the installation directory for LLVM libraries.
+
+
+
+**--cxxflags**
+
+ Print the C++ compiler flags needed to use LLVM headers.
+
+
+
+**--ldflags**
+
+ Print the flags needed to link against LLVM libraries.
+
+
+
+**--libs**
+
+ Print all the libraries needed to link against the specified LLVM
+ *components*, including any dependencies.
+
+
+
+**--libnames**
+
+ Similar to **--libs**, but prints the bare filenames of the libraries
+ without **-l** or pathnames.  Useful for linking against a not-yet-installed
+ copy of LLVM.
+
+
+
+**--libfiles**
+
+ Similar to **--libs**, but print the full path to each library file.  This is
+ useful when creating makefile dependencies, to ensure that a tool is relinked if
+ any library it uses changes.
+
+
+
+**--components**
+
+ Print all valid component names.
+
+
+
+**--targets-built**
+
+ Print the component names for all targets supported by this copy of LLVM.
+
+
+
+**--build-mode**
+
+ Print the build mode used when LLVM was built (e.g. Debug or Release)
+
+
+
+
+COMPONENTS
+----------
+
+
+To print a list of all available components, run **llvm-config
+--components**.  In most cases, components correspond directly to LLVM
+libraries.  Useful "virtual" components include:
+
+
+**all**
+
+ Includes all LLVM libaries.  The default if no components are specified.
+
+
+
+**backend**
+
+ Includes either a native backend or the C backend.
+
+
+
+**engine**
+
+ Includes either a native JIT or the bitcode interpreter.
+
+
+
+
+EXIT STATUS
+-----------
+
+
+If **llvm-config** succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value.
