#  Name:
#     ary_link

#  Purpose:
#     Generate linker (ld) arguments for linking against standalone ARY.

#  Type of Module:
#     Shell script.

#  Description:
#     This script should be invoked by those building standalone
#     applications which use ARY in order to generate the correct
#     arguments for the compiler (or ld) command. The arguments
#     generated are written to the standard output.

#  Invocation:
#     The script is normally invoked as part of a compiler command line,
#     such as:
#
#        gcc -o program -L/star/lib `ary_link` program.c
