The search service can find package by either name (apache), provides(webserver), absolute file names (/usr/bin/apache), binaries (gprof) or shared libraries (libXm.so.2) in standard path. It does not support multiple arguments yet...
The System and Arch are optional added filters, for example System could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system.
'File::Find' is great, but constructing the 'wanted' routine can sometimes be a pain. This module provides a 'wanted'-writer, using syntax that is directly mappable to the _find_ command's syntax. Also, I find myself (heh) frequently just wanting the list of names that match. With 'File::Find', I have to write a little accumulator, and then access that from a closure. But with 'File::Finder', I can turn the problem inside out. A 'File::Finder' object contains a hash of 'File::Find' options, and a series of steps that mimic _find_'s predicates. Initially, a 'File::Finder' object has no steps. Each step method clones the previous object's options and steps, and then adds the new step, returning the new object. In this manner, an object can be grown, step by step, by chaining method calls. Furthermore, a partial sequence can be created and held, and used as the head of many different sequences.
