Perlbrew is a tool to manage multiple perl installations in your
$HOMEdirectory. They are completely isolated perl universes. This approach has many benefits:
- No need to run
sudoto install CPAN modules, any more.
- Try the monthly released new perls.
- Learn new language features.
- Test production code.
- Leave vendor perl (the one that comes with OS) alone
- Hacking perl internals.
- Just to keep up with fashion.
While the default is good enough, you may customize it to install to alternative places, or even let multiple users share the whole perlbrew environment.
