Delphi source project obfuscator. 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. If you don't want your Delphi programming being visible to bad guys, then you would rather maintain well-formed source projects while releasing ever-changing AltDel-obfuscated versions.
