+# Usage:
+
+# edit your theme, find the line beginning:
+#
+# prompt = "..."
+#
+# and add the string `$prompt_additional' somewhere inside it.
+# If using the default: prompt = "[$*] ", then a good value would be:
+#
+# prompt = "[$*$prompt_additional] "
+#
+# Then place this script to your ~/.irssi/scripts directory (~/.irssi/scripts/)
+# and symlink it to the ~/.irssi/scripts/autorun directory (which may need to
+# be created first)
+#
+# You can also load it manually once the theme has been edited via
+#
+# /script load prompt_info.pl
+#
+# You will also need to reload your theme with the following command:
+#
+# /script exec Irssi::themes_reload()
+#
+# Once loaded, you can modify your prompt content by using the following command:
+#
+# /set_prompt <string>
+#
+# You can also use it from other scripts by issuing a signal as follows:
+#
+# Irssi:signal_emit('change prompt',
+#
+# report bugs / feature requests to http://github.com/shabble/irssi-scripts/issues
+#
