+#
+# This shell script provides a wrapper for ld under AIX in order to
+# create the .exp file required for linking. Its arguments consist
+# of the name and arguments that would normally be provided to the
+# ld command. This script extracts the names of the object files
+# from the argument list, creates a .exp file describing all of the
+# symbols exported by those files, and then invokes "ldCmd" to
+# perform the real link.
+
+# Extract from the arguments the names of all of the object files.

+# Create the export file from all of the object files, using nm followed
+# by sed editing. Here are some tricky aspects of this:
+#
+# - Use the -X32_64 switch to nm to handle 32 or 64bit compiles.
+# - Eliminate lines that end in ":": these are the names of object files
+# - Eliminate entries with the "U" key letter; these are undefined symbols
+# - If a line starts with ".", delete the leading ".", since this will just
+# cause confusion later
+# - Eliminate everything after the first field in a line, so that we're
+# left with just the symbol name
