* for example, the Makefile for the Gryphon plugin, so it knows
* where to install the plugin.
*
* Eventually, we should probably have an "epan-configure" script
* (or "libethereal-configure", or whatever), along the lines of what
* GTK+ and GLib have, that can print, among other things, the directory
* into which plugins should be installed. That way, only libethereal
* need know what directory that is; programs using it won't, *and*
* Makefiles for plugins can just use "epan-configure" to figure out
* where to install the plugins.
*
* (Would that *more* libraries had configure scripts like that, so
* that configure scripts didn't have to go through various contortions
* to figure out where the header files and libraries for various
