custom_index does not show up in my plugin list

I want to activate the plugin custom_index, however, when I go to Administration and select plugins it is NOT in the list. The folder custom_index is in the mod folder and its contents are there. Anyone with ideas of why it would not show up in the plugin list?

thanks,

Shimon
