+XCOMM Construct shared-library export lists for IBM-AIX based on standardized
+XCOMM export list description file
+XCOMM
+XCOMM Usage: elistgen libfoo.sl libfoo.elist > libfoo.lopt
+XCOMM
+XCOMM	libfoo.a     => shared library of interest
+XCOMM	libfoo.elist => Meta description of necessary export list.
+XCOMM
+XCOMM    The output file, "libfoo.lopt" may then be passed to the IBM linker to 
+XCOMM    reconstruct the shared library, libfoo.sl.
