Usage: apu-$APRUTIL_MAJOR_VERSION-config [OPTION]

Known values for OPTION are:
  --prefix[=DIR]    change prefix to DIR
  --bindir          print location where binaries are installed
  --includes        print include information
  --includedir      print location where headers are installed
  --ldflags         print linker flags
  --libs            print library information
  --avoid-ldap      do not include ldap library information with --libs
  --ldap-libs       print library information to link with ldap
  --avoid-dbm       do not include DBM library information with --libs
  --dbm-libs        print additional library information to link with DBM
  --srcdir          print APR-util source directory
  --link-ld         print link switch(es) for linking to APR-util
  --link-libtool    print the libtool inputs for linking to APR-util
  --apu-la-file     print the path to the .la file, if available
  --old-expat       indicate if APR-util was built against an old expat
  --db-version      print the DB version
  --version         print APR-util's version as a dotted triple
  --help            print this help

When linking with libtool, an application should do something like:
  APU_LIBS="\`apu-$APRUTIL_MAJOR_VERSION-config --link-libtool --libs\`"
or when linking directly:
  APU_LIBS="\`apu-$APRUTIL_MAJOR_VERSION-config --link-ld --libs\`"

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