Usage: apu-config [OPTION]

Known values for OPTION are:
  --prefix[=DIR]    change prefix to DIR
  --bindir          print location where binaries are installed
  --includedir      print location where headers are installed
  --libdir          print location where libraries are installed
  --cc              print C compiler name
  --cpp             print C preprocessor name and any required options
  --ld              print C linker name
  --cflags          print C compiler flags
  --cppflags        print cpp flags
  --includes        print include information
  --ldflags         print linker flags
  --libs            print additional libraries to link against
  --srcdir          print APR-util source directory
  --installbuilddir print APR-util build helper directory
  --link-ld         print link switch(es) for linking to APR-util
  --apu-so-ext      print the extensions of shared objects on this platform
  --apu-lib-file    print the name of the aprutil lib
  --version         print the APR-util version as a dotted triple
  --help            print this help

When linking, an application should do something like:
  APU_LIBS="\`apu-config --link-ld --libs\`"

An application should use the results of --cflags, --cppflags, --includes,
and --ldflags in their build process.
