+# lrztar
+
+> A wrapper for `lrzip` to simplify compression of directories.
+> See also: `tar`, `lrzuntar`, `lrunzip`.
+
+- Archive a directory with `tar`, then compress:
+
+`lrztar {{path/to/directory}}`
+
+- Same as above, with ZPAQ - extreme compression, but very slow:
+
+`lrztar -z {{path/to/directory}}`
+
+- Specify the output file:
+
+`lrztar -o {{path/to/file}} {{path/to/directory}}`
+
+- Override the number of processor threads to use:
+
+`lrztar -p {{8}} {{path/to/directory}}`
+
+- Force overwriting of existing files:
+
+`lrztar -f {{path/to/directory}}`
