dnl
dnl Optional WX-LIBS argument contains comma- or space-separated list of

# 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).
#
#  dllar is free software; you can redistribute it and/or modify
#  it under the terms of the GNU General Public License as published by

# 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

#  - GNU text utilites (cat, sort, uniq)
#    used to process emxexp output
