Usage: apr-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
  --cc              print C compiler name
  --cpp             print C preprocessor name and any required options
  --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 source directory
  --installbuilddir print APR build helper directory
  --link-ld         print link switch(es) for linking to APR
  --link-libtool    print the libtool inputs for linking to APR
  --shlib-path-var  print the name of the shared library path env var
  --apr-la-file     print the path to the .la file, if available
  --apr-so-ext      print the extensions of shared objects on this platform
  --apr-lib-target  print the libtool target information
  --apr-libtool     print the path to APR's libtool
  --version         print the APR's version as a dotted triple
  --help            print this help

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

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