AltDel is a 5-phase script-driven lexical compiler that produces obfuscation by lowering the language level of Delphi source projects. The obfuscation of Delphi projects is a deterrent against reverse engineering. Delphi executables are easy to reverse-engineer because they carry a lot of source code information. Good Delphi decompilers reconstruct whole projects, forms, source names, strings, and all.
