+# Description: An almost fully POSIX compliant batch file renamer
+#
+# Note: nnn auto-detects and invokes this plugin if available
+#       Whitespace is used as delimiter for read.
+#       The plugin doesn't support filenames with leading or trailing whitespace
+#       To use NNN_LIST your shell must support readlink(1)
+#
+# Capabilities:
+#    1. Basic file rename
+#    2. Detects order change
+#    3. Can move files
+#    4. Can remove files
+#    5. Switch number pairs to swap filenames
+#
+# Shell: bash
+# Author: KlzXS
+
+# shellcheck disable=SC1090,SC1091
