# This script is a completely rewritten version of the cernlib script supplied
# with the original CERNLIB source.  It now does recursive library dependency
# checking, removes duplicate entries, and makes breakfast. (Well, not really.)
# This script is provided under the GNU General Public License.

# I have tried to maintain cross-platform compatibility, but I don't have
# any other architectures handy to test things on, so it might have broken.
# But this is not a big deal, since it's doubtful that someone would use
# Debian packages on HP-UX, Solaris, etc. anyway.

	Usage: cernlib [OPTIONS] LIBRARIES
	List the linker options required to compile a CERNLIB program with the given
	library dependencies.  Example: "cernlib -G Motif pawlib" on Linux outputs
	"-Wl,-static -lpawlib-lesstif -lpawlib -lmathlib -lgraflib -lpacklib-lesstif
	 -lgrafX11 -lpacklib -lkernlib -Wl,-dy -L/usr/X11R6/lib -lXbae -lXm -lXaw
	 -llapack -lm -lXt -lX11 -lnsl -lcrypt -ldl -lgfortran".
	
	  -a <arch>	Specify an architecture, e.g. Linux (default), AIX, HP-UX, etc.
	  -dy, -safe	Don't assume CERN libraries should be linked against statically.
	  		This flag is also required when using the compiler -static flag.
	  -G <driver>	Specify a graphics driver.  Options: X11, Motif, GPHIGS,
	  		GKS, GL, GPR.  Only the first two are available on Linux.
	  -P, -s	Ignored; for backwards compatibility.
	  -u		Do not include arch-specific libraries in the output.
	  -v <version>	Specify version of \$CERN_LEVEL.  This is meaningless unless
	  		you have installed non-Debian versions of CERNLIB.  In that
	                case you should export \$CERN or \$CERN_ROOT first.
	  -?, --help	Print this help message and exit.
