Opener 3.3 is a Multi-Architecture Binary (i.e., "fat").  It runs on machines running NeXTSTEP 3.1 or later, Intel i386-based PCs, HP/PA-RISC based machines, and Sun Sparc based machines.

Opener is a utility that is indispensible for unpacking or creating common kinds of archived files (.tar, .tar.Z, .shar, .zip, .arc, .arj, .zoo, .gz, etc.).  See Opener.app/HelpOpener/General.rtfd for details.

The first package contains the app and utility binaries.
The second package contains all source files and utility binaries necessary for building.
The third (utils) package contains all source for the public-domain utilities 
used by Opener, including any (for example) Makefile changes that were 
necessary to compile "fat".  It also contains all the test files.

To install, unpack and drop Opener.app into an Apps folder.

Differences from Opener 3.2a:
	- Added .gnutar.gz, .gnutar.z support to Opener.table
	- Moved .gz after all other extensions ending in .gz in Opener.table to 
	  avoid a search order dependence problem.  Creating a .tar.gz
	  appeared to work but really only created a .gz.
    - Added -appWillInit: to fix first-time-in bug.  Opener only opened a
	  file once already launched.
	- Split out app source files as separate archive from app
	- Split out test files and put them in Opener_utils part of distribution
	- Revamped Help
	- Suggestion no longer overwrites a pending Mail compose window's contents

Differences from Opener 3.2:
	- Fixed bug in setting of default directory preference (really this time!)
	- Added .mime to Opener.table and Controller.m (omitted before)
	- Added docAu.tiff to project and to app wrapper (omitted earlier)
