Usage: pearl-config [OPTION]

Known values for OPTION are:

  --cxxflags		print preprocessor and compiler flags for PEARL
  --libs[=COMPONENT]	print library linking information for PEARL

The optional COMPONENT argument of the '--libs' option is used to select the
PEARL components to be used (comma-separated list). The 'base' component is
always preselected. Recognized component names for this installation of PEARL
are:
  base       (preselected)
