Usage: apreq2-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
  --srcdir          print apreq2 source directory
  --link-ld         print link switch(es) for linking to libapreq2
  --link-libtool    print the libtool inputs for linking to libapreq2
  --la-file         print the path to the library's .la file, if available
  --library-version print the libapreq2 library version as a dotted triple
  --package-version print the version of the distribution
  --package-name    print the distribution file's name
  --package-title   print the full name of the release
  --help            print this help

When linking with libtool, an application should do something like:
  APREQ_LIBS="\`apreq2-config --link-libtool --libs\`"
or when linking directly:
  APREQ_LIBS="\`apreq2-config --link-ld --ldflags --libs\`"

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