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