+# Description: Run custom search and list results in smart context
+#
+# Note: This plugin retains search history
+#
+# Usage:
+#   Run plugin and enter e.g. "-size +10M" to list files in current
+#   directory larger than 10M. By default entered expressions are
+#   interpreted as arguments to find. Results have to be NUL
+#   terminated which is done by default for find. Alternatively one
+#   can prepend a '$' to run a custom search program such as fd or
+#   ripgrep. Entered expressions will be saved in history file to
+#   be listed as bookmarks and and can be entered by index and edited.
+#
+# Shell: Bash
+# Author: Arun Prakash Jana, Luuk van Baal
