I don't know what the best approach would be to allow the following:

I would like a program P to use a module M.pm, and they currently (and always will) reside together in the same directory. I would like to be able to rename that directory and have it still work. I would also like to be able to run P from an arbitrary location, such that $CWD is not predictable. The code below does not satisfy these two requirements.

Here is the program that resides in ~/P:

  #! /usr/bin/perl -w
  use strict;
  use M;
  my $m = M->new;
[download]

and here is the module 'M' that resides in ~/M.pm:

  package M;
  sub new {1};
  1;
[download]

I have considered:

• an install-time patching of the shebang to include the correct current path
• an install-time patching of a config file with the lib path
• some fiddling with $0, and unshifting the dir onto @INC

Can anyone suggest something better?
