Ooops,

merlyn, I do not belive that. Please explain further, because I would say everybody looses if you use lib.

My experience tells me, to avoid hardcoded variables whenever possible, especially paths to files, for the following reasons:

1. if you move the script, it possibly does not run anymore, the path does not exist for a different user on the network. So you have to modify the script and have dozens of version after a while. (Think of big networks, different usergroups with access rights etc.)

2. You have a testbed with your modules and a different production environment. You will have to modify your programm after the release-test.For the stuff with legal impacts, I will never get through revision, even if I do the same with PERL5LIB, because of the remaining risk of further changes.

3. use lib is at the beginning, other constants maybe not, but somewhere hidden in a module etc. This is hard to maintain.

4. You have a well coded script, that can be used for different purposes, you change a setting in an ini-file instead of the code itself.

5. customization or internationalization can be solved with a module on a different path (use Perl code to set constants). You have to switch the path maybe repeatedly.

etc. etc.

But for the use lib; I consider the discussion not necessary, because it is quite easy to avoid it most times:
- have the modules in a subdirectory
- install them properly, so they are in .../site/lib and in the path beneath the runtime.
