+The lz script emulates and extends the lz and uz commands of the mtools.
+
+It handles: .tar, .tar.gz, .tar.bz2, .tar.xz and .tar.lzma, through the
+standards options of GNU tar.
+
+If the script name is "lz", the archive content is displayed. If the name
+is "uz", it is extracted.
+
+To install lz and uz, move put script in a directory in the PATH (for
+instance /usr/local/bin) and hard link it to uz:
+  cp lz /usr/local/bin
+  ln /usr/local/bin/{lz,uz}
