+## Features
+
+The following cabal flags of `libarchive-clib` control unpacking features:
+
+* zlib: Build support for gzip through zlib (default enabled)
+* iconv: Link against iconv (default disabled)
+* lz4: Build support for lz4 through liblz4 (default disabled)
+* zstd: Build support for zstd through libzstd (default disabled)
+* lzma: Build support for xz through lzma (default disabled)
+* bz2lib: Build support for bzip2 through bz2lib (default disabled)
+* acl: Enable ACL support (default disabled)
+* xattr: Extended Attributes support (default disabled)
+
+At least `zlib` is necessary to unpack zip archives.
+
+You can force it in `cabal.project` as such:
+
+```
+package libarchive-clib
+  flags: +zlib
