EiffelStudio

# Release notes for EiffelStudio 5.1

## Graphical environment

- Numerous improvements in usability and bug fixes.
- Richer class and cluster creation dialogs.
- Class name completion in the editor (by pressing Ctrl+Shift+Space half-way through the class name).
- Editor now supports drag-and-drop of the selection.
- When debugging a project from EiffelStudio, the current directory will be your project directory. It is a change from previous version where:
  - on Windows, it used to be launched in the W_code subdirectory of your project directory
  - on Unix, it used to be launched from the same directory where `estudio' (or `ebench') was launched.
- EiffelStudio GUI now also available on Unix platforms and Windows 9x/Me

- Added make_temporary_name in FILE_NAME
- Made to_c obsolete from class INTEGER_INTERVAL
- Changed semantic of split from class STRING
