We will be documenting this soon.

Basically, [PREFIX-exec routine] allows you to call a compiled subroutine
inside a loop, item-list, search-list, etc. This is much faster than
using [perl] or [calc] regions. The routine can be defined inline:

	[PREFIX-sub bar_link]
	 # Put some perl code here

or be preloaded as a Sub in catalog.cfg.

The bar_link routine in use is in INTERCHANGE_ROOT/catalog_before.cfg.
If you copy it to your catalog.cfg and modify it, it will only apply
to your catalog while the other is still in force for others.
