Because WRI doesn't have the slightest interest in giving users a coherent
description of how to write packages, where to put them, and how to load

Basically, you have to put the package in a folder in your private
Applications folder and then include the folder name in the Needs statement
as a leading context.

The Presentations package gives an example of a package with extensive
annotation and explanation, and shows where to put it and how to load it.
There is also an essay on writing packages.

according to comment at the top of autosaved packages, these files can  
be loaded using Needs[] instead of Get[].

(* This file was generated automatically by the Mathematica front  
end.  *)
(* It contains Initialization cells from a Notebook file,  
which         *)
(* typically will have the same name as this file except ending  
in      *)
(* ".nb" instead of  
".m".                                               *)
(*                                                                      *)
(* This file is intended to be loaded into the Mathematica kernel  
using *)
(* the package loading commands Get or Needs.  Doing so is  
equivalent   *)
(* to using the Evaluate Initialization Cells menu command in the  
front *)
end.                                                                 *)

it doesn't work for me...

	Needs::cxt: Invalid context specified at position 1 in  
Needs[phd_thesis_common.m]. A context must consist of valid symbol  
names separated by and ending with `. >>

any help/suggestions appreciated.
