//
//  The mechanism can be used by IDEs or non-public code bases to integrate with
//  their build system. Currently we support statically linking in an
//  implementation of \c findCompilationDatabaseForDirectory and enabling it
//  with -DUSE_CUSTOM_COMPILATION_DATABASE when compiling the Tooling library.
//
//  FIXME: The strategy forward is to provide a plugin system that can load
//  custom compilation databases and make enabling that a build option.
