+# cp plugin
+
+This plugin defines a `cpv` function that uses `rsync` so that you
+get the features and security of this command.
+
+To enable, add `cp` to your `plugins` array in your zshrc file:
+
+```zsh
+plugins=(... cp)
+```
+
+## Description
+
+The enabled options for rsync are:
+
+- `-p`: preserves permissions.
+
+- `-o`: preserves owner.
+
+* `-g`: preserves group.
+
+* `-b`: make a backup of the original file instead of overwriting it, if it exists.
+
+* `-hhh`: outputs numbers in human-readable format, in units of 1024 (K, M, G, T).
+
+* `--backup-dir=/tmp/rsync`: move backup copies to "/tmp/rsync".
+
+* `-e /dev/null`: only work on local files (disable remote shells).
+
+* `--progress`: display progress.
+
+* `--`: everything after this is an argument, even if it starts with a hyphen.
