% minor optimization to last change. checkme.
- contrib/hbxlsxml
+ examples/hbxlsxml
! moved to examples. this code is not even close
to Harbour code quality and implements not .xls
file format but HTML format renamed to .xls. It's
not understood by lots of tools, it's not a standard.
see details on list.
