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