#
# 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
# (used to build the .dll)
# - emxexp
# (used to create .def file from .o files)
# - emximp
# (used to create .a file from .def file)
# - GNU text utilites (cat, sort, uniq)
# used to process emxexp output
# - GNU file utilities (mv, rm)
# - GNU sed
# - lxlite (optional, see flag below)
# (used for general .dll cleanup)
