For completeness, yet another alternative that is simpler for
self-contained executables (more popular on Win32) is embedding
source or binary chunks and compressing it. With UPX, UCL-max is
about gzip-6, plus new versions of UPX has LZMA, suitable for
contemporary desktop machines. For the developer, no extra code
needs to be written.
