+# 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).
+#

+# To successfuly run this program you will need:
+# - Current drive should have LFN support (HPFS, ext2, network, etc)
+# (Sometimes dllar generates filenames which won't fit 8.3 scheme)
+# - gcc
