Revision 1.3 2005/02/08 12:31:36 marc
new static methods to simplify access to options
Revision 1.2 2004/11/25 18:26:04 marc
Constness corrected
Revision 1.1 2004/08/28 16:13:42 marc
mrw-c++-0.92 (mrw)
- new file: version.cxx
- new file header for all sources
- work around warning in mrw::auto
- possibility to compile without log4cxx
- work around bugs in demangle.h and libiberty.h
- corrections in documentation
- added simple tracing mechanism
- more warnings
- small corrections in Auto<>::Free and a new test for it
- possibility to compile without stack trace
