+# XZ (Lempel-Ziv-Markov chain-Algorithm) file format supported by:
+#   - 7-Zip <http://7-zip.org/>
+#   - LZMA SDK <http://7-zip.org/sdk.html>
+#   - LZMA Utils <http://tukaani.org/lzma/>
+#
+# Note that this is different format than the original format created
+# by LZMA_Alone from older versions of LZMA SDK. These files are
+# non-trivial to detect, because they have no magic bytes.
