// ----------------------- OEObject Class Interface ---------------------------

//

// Original class (ObjectError) by:

// Bill Bumgarner, Andrew Stone, Mike Morton, and Julie Zelenski

//

// A class that poses as object and does crash-reporting.

// Catches terminating signals (ie seg faults, bus errors)

// and fatal Objective-C runtime errors and writes a backtrace

// out to the console using some shady hacks.  This could be modified

// to write backtrace to a file, mail message, etc... if desired.

//

// Modified by Ivo Rothschild (ivo@hasc.ca) to try to continue

//			when muddling on.

//

// Attempted port to OpenStep by Subrata Sircar (subrata_sircar@next.com).

//

// Attempted enhancements for OS/NT by Art Isbell (arti@lava.net).

//

// Use at own Risk (so sayeth the authors).

//

// NO WARRANTY:

// ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE

// IS HEREBY DISCLAIMED.  IN NO EVENT WILL THE AFOREMENTIONED PARTIES BE LIABLE

// FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL

// DAMAGES ARISING OUT OF THE USE OF OR INABILITY TO USE THIS CODE.

// The following mess is brought to you by Microsoft :-(  If OEObject is

// defined in a framework, then _OEOBJECT_BUILDING_DLL (or your own equivalent)

// must be defined when the framework is being built and OE_EXTERN must be

// defined as OEOBJECT_EXTERN (or your own equivalent).

// However, if OEObject is defined in the main project, OE_EXTERN should be

// defined as OEOBJECT_PRIVATE_EXTERN (or your own equivalent).
