+# dllar - a tool to build both a .dll and an .a file
+# from a set of object (.o) files for EMX/OS2.
+#
+#  Written by Andrew Zabolotny, bit@freya.etu.ru
+#  Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
+#
+#  This script will accept a set of files on the command line.
+#  All the public symbols from the .o files will be exported into
+#  a .DEF file, then linker will be run (through gcc) against them to
+#  build a shared library consisting of all given .o files. All libraries
+#  (.a) will be first decompressed into component .o files then act as
+#  described above. You can optionally give a description (-d "description")
+#  which will be put into .DLL. To see the list of accepted options (as well
+#  as command-line format) simply run this program without options. The .DLL
+#  is built to be imported by name (there is no guarantee that new versions
+#  of the library you build will have same ordinals for same symbols).
