Usage: ace-config OPTION [OPTIONS...] [LIBRARY]

Generic options:
  --version	output ACE version information
  --help	display this help and exit

Compilation support options:
  --cxx         print C++ compiler used for compiling
  --cxxflags	print C++ pre-processor and compiler flags
  --libs	print library linking information
  --libs-only-L	only print the -L/-R part of --libs
  --libs-only-l only print the -l part of --libs

Install directories ACE was configured with:
  --prefix  --exec-prefix  --bindir  --sbindir  --libexecdir  --datadir
  --sysconfdir  --sharedstatedir  --localstatedir  --libdir  --infodir
  --mandir  --includedir

Known values for LIBRARY are:

    ace
    netsvcs
    tao         (calls tao-config)

If LIBRARY is none of these,
    
    ${libdir}/<LIBRARY>Conf.sh

is looked in for the necessary information.
