IDE for Free Pascal - LCL source code

 Lazarus is an IDE to create (graphical and console) applications with Free
 Pascal, the (L)GPLed Pascal and Object Pascal compiler that runs on
 Windows, Linux, Mac OS X, FreeBSD and more.
 .
 Lazarus is the missing part of the puzzle that will allow you to develop
 programs for all of the above platforms in a Delphi-like environment.
 The IDE is a RAD tool that includes a form designer.
 .
 Unlike Java's "write once, run anywhere" motto, Lazarus and Free Pascal
 strive for "write once, compile anywhere". Since the exact same compiler
 is available on all of the above platforms you don't need to do any recoding
 to produce identical products for different platforms.
 .
 In short, Lazarus is a free RAD tool for Free Pascal using its Lazarus
 Component Library (LCL).
 .
 This package contains the latest version of the source code necessary for
 the IDE code tool to work properly (retrieving declarations and navigating
 in code).
