Using the package command breaks up things into different namespaces.
For instance you could:
package my_package;
# do something
#do somethingelse
Puts both #do something and #do something else in the my_package
namespace. On the other hand:
{
package my_package;
# do something
}
#do somethingelse
Only puts #do something in the my_package namespace.
This allows you to create functions and files that don't step on
anybody's feet. For instance:
$foo = 50;
{
package my_package;
my $foo = 100;
}
Would create two different versions of $foo
$foo == 50
while
$my_package::foo == 100
You can seperate packages into seperate files ending them in .pm and
naming them with the package name and then:
use my_package; # allows access to my_package
