# Since csh/tcsh doesn't have functions, this script can be used to manage
# slightly more complex logic.
#
# Resolves for the existence of DIR/lib64 and DIR/lib, or uses the fallback
# LIBEXT if these failed. A DIR ending in "-none" or "-system" is skipped.
#
# output -csh: setenv LD_LIBRARY_PATH dir/lib:$LD_LIBRARY_PATH
# output -make: -Ldir/lib
# output -sh: LD_LIBRARY_PATH=dir/lib:$LD_LIBRARY_PATH

cat<<USAGE
Usage: ${0##*/} [OPTION] DIR [LIBEXT]
options:
-sh Emit POSIX shell syntax (default)
-csh Emit C-shell shell syntax
-sh-verbose As per -sh, with additional verbosity
-csh-verbose As per -csh, with additional verbosity
-make Emit content for a makefile
-help Print the usage
Resolves for the existence of DIR/lib64 and DIR/lib, or uses the fallback
LIBEXT if these failed. A DIR ending in "-none" or "-system" is skipped.
With -sh LD_LIBRARY_PATH=dir/lib:\$LD_LIBRARY_PATH
With -csh setenv LD_LIBRARY_PATH dir/lib:\$LD_LIBRARY_PATH
With -make -Ldir/lib
