%description
This package has two programs to wrap a rexx program in either a VIO
(commandline) or PM (presentation manager) executable. You probably know
some other rexx -> exe converters like VXRexx, Vispro, REXX2EXE,...
Features of this implementation:
 - build from assembler source: small size - comes close or is below
   the size of the wrapped rexx, less processing overhead and memory usage
 - turns the rexx scripts into plain executable resources - no need to
   compress the resources since the OS build in page compression can be
   used. Use LxLite to squeeze the last byte from the executable..
   I also see no need to encrypt a rexx script. Since there is nothing
   'compiled' or tokenized, the rexx program should be portable between
   different OS/2 rexx interpreter versions and lines.

%changelog
* Fri Jun 9 2017 Dmitriy Kuminov <coding@dmik.org> 1.0.0-2
- Hardcode helper path to converters as `parse source` does not contain a full
  path when CMD is converted to EXE and started by name w/o any path.

* Thu Jun 8 2017 Dmitriy Kuminov <coding@dmik.org> 1.0.0-1
- Store binary distribution on github for easy patching.
- Change epoch to 1 due to changed versioning scheme.
- Fix converter execution failure with no arguments.
- Use single source base for both rexx2vio.cmd and rexx2pm.cmd.
- Properly handle errors and use output EXE dir for temp files instead of TMP.
- Prefer RC16.EXE to RC.EXE when choosing resource compiler.
- Install VIO/PM stubs and helper script to usr/lib/rexx_exe instead of usr/bin.
- Depend on os2tk45 that provides RC16.EXE.

* Thu Sep 08 2011 yd
- use a temporary name for resource files, fixes smp builds.
