  33
  34 C4::ItemType - objects from the itemtypes table
  35
  36 =head1 SYNOPSIS
  37
  38     use C4::ItemType;
  39     my @itemtypes = C4::ItemType->all;
  40     print join("\n", map { $_->description } @itemtypes), "\n";
  41
  42 =head1 DESCRIPTION
  43
  44 Objects of this class represent a row in the C<itemtypes> table.
  45
  46 Currently, the bare minimum for using this as a read-only data source has
  47 been implemented.  The API was designed to make it easy to transition to
  48 an ORM later on.
