parallel threads with ForkManager - example needed

[Kalin Evtimov]

Hi!
I am trying to start three parallel processes and I am using the module Paralle::ForkManager for this purpose.
Does anybody have experience with this module. I do not understand very well how to use it from the example on the CPAN-page. I need a small example or something like this.
I want to run 3 different commands, not three times the same, as shown in the example.
Will be greatful for any help.

Regards,

Kalin
