"Lazarus the open source answer to Borland Delphi has
released version 0.5 of it's IDE."
"Lazarus is a RAD Object Pascal Development IDE for use with
Free Pascal. At this point a large portion of the Delphi VCL has
been implemented in the LCL (Lazarus Class Libraries). Lazarus is
designed to work on any platform where Free Pascal can be found.
That includes Linux, Windows, OS/2, DOS plus more on the way. The
LCL is designed to be widget independent. At present interfaces for
GTK+, Qt, and Win32 are in development. In the future interfaces
for KDE, Gnome and other libraries will be available. The widget
set used is determined by which one you compile and link against.
No code changes are required."
