Sphinx docs with Furo theme covering CLI usage, library API reference,
archive format specification, build instructions, history, and roadmap.
GitHub Actions workflow deploys to Pages on push to main.
Test corpus (empty, text, binary, compressible, incompressible) with
reference archives created by original UC2 v2.3 in DOSBox. Two CTest
tests: test_identify (magic detection) and test_extract (full
extraction pipeline verified byte-for-byte against corpus).
Restructure compat layer: #include_next headers moved to posix/ for
MinGW, new standalone headers in msvc/ for MSVC (unistd.h, utime.h,
getopt.h). Add getopt() implementation, chmod/unlink/chdir compat
functions, MSVC CRT initializer for UTF-8 console, _pgmptr fix.
Add a DJGPP CMake toolchain file and DOS compatibility layer (err.h,
fnmatch, getprogname/setprogname) so UC2 builds as a native DOS
executable via cross-compilation from Linux. The toolchain works
around a baked-in /usr/include in the DJGPP GCC binary by using -I
instead of -isystem to ensure DJGPP headers take precedence.
Add GitHub Actions CI workflow that builds and smoke-tests on both
ubuntu-latest and macos-latest.
