Internal Program Version: ExtUtils::CChecker  0.11.5.38.2

Often Perl modules are written to wrap functionality found in existing C
headers, libraries, or to use OS-specific features. It is useful in the
_Build.PL_ or _Makefile.PL_ file to check for the existance of these
requirements before attempting to actually build the module.

Objects in this class provide an extension around ExtUtils::CBuilder to
simplify the creation of a _.c_ file, compiling, linking and running it, to
test if a certain feature is present.

It may also be necessary to search for the correct library to link against,
or for the right include directories to find header files in. This class
also provides assistance here.
