# 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.
