10# dllar - a tool to build both a .dll and an .a file
11# from a set of object (.o) files for EMX/OS2.
12#
13#  Written by Andrew Zabolotny, bit@freya.etu.ru
14#  Ported to Unix like shell by Stefan Neis, Stefan.Neis@t-online.de
15#
16#  This script will accept a set of files on the command line.
17#  All the public symbols from the .o files will be exported into
18#  a .DEF file, then linker will be run (through gcc) against them to
19#  build a shared library consisting of all given .o files. All libraries
20#  (.a) will be first decompressed into component .o files then act as
21#  described above. You can optionally give a description (-d "description")
22#  which will be put into .DLL. To see the list of accepted options (as well
23#  as command-line format) simply run this program without options. The .DLL
24#  is built to be imported by name (there is no guarantee that new versions
25#  of the library you build will have same ordinals for same symbols).

42# To successfuly run this program you will need:
43#  - Current drive should have LFN support (HPFS, ext2, network, etc)
44#    (Sometimes dllar generates filenames which won't fit 8.3 scheme)
45#  - gcc
46#    (used to build the .dll)
47#  - emxexp
48#    (used to create .def file from .o files)
49#  - emximp
50#    (used to create .a file from .def file)
51#  - GNU text utilites (cat, sort, uniq)
52#    used to process emxexp output
53#  - GNU file utilities (mv, rm)
54#  - GNU sed
55#  - lxlite (optional, see flag below)
