+#!/bin/bash
+# emerge-current.sh by Hellf[i]re
+#
+# This script is designed to read the name of the last package compiled.
+#
+# As this script does read the entirety of emerge.log, it will be rather
+# heavy on the CPU. It shouldn't be enough to be noticable on newer (2.0Ghz+)
+# processors, but it still should not be run more often than every 30 seconds.
+#
+# Usage:
+# .conkyrc: ${execi [time] /path/to/script/emerge-current.sh}
+#
+# Usage Example
+# ${execi 30 /home/youruser/scripts/emerge-current.sh}
