Hi maximus !!

Already lot of discussions hav gone into this topic.. But i thought of adding some of my points to that

Ther r lots of ways to deal with sloppy code.. You can maintain uniformity in code developed by your developers ..

You can clean up your code using perltidy. Download it from sourceforge
Read the documentation too.. Another thing i would suggest is to make use of

Perl checkstyle module
[download]

Do refer the Module::CheckStyle in CPAN
This module has got lot of configuration options.. the only thing u need to do is to give the path of your .pl file while using this module ...

Your script can also be documented using PODs ..

Thats it man !!!

Thank you ,
