  29 C4::ItemType - objects from the itemtypes table
  30
  31 =head1 SYNOPSIS
  32
  33     use C4::ItemType;
  34     my @itemtypes = C4::ItemType->all;
  35     print join("\n", map { $_->description } @itemtypes), "\n";
  36
  37 =head1 DESCRIPTION
  38
  39 Objects of this class represent a row in the C<itemtypes> table.
  40
  41 Currently, the bare minimum for using this as a read-only data source has
  42 been implemented.  The API was designed to make it easy to transition to
  43 an ORM later on.

  52
  53 Given a hashref, a new (in-memory) C4::ItemType object will be instantiated.
  54 The database is not touched.
