Various packages suggest they should be installed in subdirectories of 
ExtraPackages.  For example, Ersek's RootSearch.m, is to be installed in 
subdirectory Enhancements of ExtraPackages.

I keep all such 3rd party add-ons in a directory tree separate from the 
Mathematica install directory tree.  Namely, in a directory to which 
$UserBaseDirectory points.  Thus, RootSearch.m is in directory:

   ToFileName[{$UserBaseDirectory, "ExtraPackages", "Enhancements"}]

Yet still a command such as

   <<Enhancements`RootSearch`

or

   Needs["Enhancements`RootSearch`"]

fails to find its target.

How can I make this work?

Platform: Mathematica 5.1 for Windows (XP).
