-# ========================================================================
-# FILE: ld_so_aix
-# TYPE: executable, uses makexp_aix
-# SYSTEM: AIX
-#
-# DESCRIPTION: Creates a shareable .o from a set of pre-compiled 
-# (unshared) .o files
-#
-# USAGE: ld_so_aix [CC] [arguments]
-#
-# ARGUMENTS: Same as for "ld". The following arguments are processed
-# or supplied by this script (those marked with an asterisk
-# can be overriden from command line):
-#
-# Argument Default value
-# (*) -o [OutputFileName] -o shr.o
-# (*) -e [EntryPointLabel] -e init[OutputBaseName]
-# (*) -bE:[ExportFile] -bE:[OutputBaseName].exp
-# (*) -bI:[ImportFile] -bI:./python.exp
-# -bM:[ModuleType] -bM:SRE
-# -bhalt:[Number] -bhalt:4
-# -T[Number] -T512
-# -H[Number] -H512
-# -lm
-#
-# The compiler specific ("-lc" or "-lc_r", "-lpthreads",...)
-# arguments will be automatically passed to "ld" according
-# to the CC command provided as a first argument to this
-# script. Usually, the same CC command was used to produce
-# the pre-compiled .o file(s).
-#
-# NOTES: 1. Since "ld_so_aix" was originally written for building
-# shared modules for the Python interpreter, the -e and
-# -bI default values match Python's conventions. In
-# Python, the entry point for a shared module is based
-# on the module's name (e.g., the "mathmodule" will
-# expect an entry point of "initmath").
-# 2. The script accepts multiple .o or .a input files and
-# creates a single (shared) output file. The export list
-# that is created is based on the output file's basename
-# with the suffix ".exp".
-# 3. The resulting shared object file is left in the
-# current directory.
-# 4. Uncommenting the "echo" lines gives detailed output
-# about the commands executed in the script.
-#
-# 
-# HISTORY: Oct-1996 -- Support added for multiple .o files --
-# -- and optional arguments processing. --
-# Chris Myers (myers at tc.cornell.edu), Keith Kwok
-# (kkwok at tc.cornell.edu) and Vladimir Marangozov
-#
-# Aug-6-1996 -- Take care of the compiler specific --
-# -- args by leaving CC to invoke "ld". --
-# Vladimir Marangozov
-#
-# Jul-1-1996 -- Make sure to use /usr/ccs/bin/ld --
-# -- Use makexp_aix for the export list. --
