UC2 — UltraCompressor II
========================

A cross-platform revival of UltraCompressor II, the DOS-era archiver by
Nico de Vries (1992--1996).  UC2 was notable for its advanced
deduplication ("master blocks"), file versioning, and competitive
compression ratios on the hardware of its day.

UC2 v3 brings it back as a modern, portable C99 tool with both
decompression and compression, targeting Linux, macOS, Windows, and DOS.
