Modules

#!/usr/bin/perl -w

use MapleTreesModule;

# The compiler searches for MapleTreesModule.pm

# following all the paths in an array called @INC.

# The module is a precompiled package of the same name.

# When the “use” is executed, all the definitions in the

# package become available, and any other code in

# the package gets executed.

# Packages can be in subdirectories of searched paths:

use Net::Mail; # Mail.pm must be in Net.
