Hi Peter,

> Yes, you can use Fiji plugins in a vanilla ImageJ 1.x installation

I added a FAQ entry on it:

http://imagej.net/Frequently_Asked_Questions#How_do_I_install_a_Fiji_plugin_into_vanilla_ImageJ_1.x.3F

There are several downsides to doing things this way, which I explain
further there. In particular, it places the burden of dependency version
management on the end user, which is something Fiji was specifically
created to avoid doing.

Regards,
Curtis
