  29 C4::Category - objects from the categories table
  30
  31 =head1 SYNOPSIS
  32
  33     use C4::Category;
  34     my @categories = C4::Category->all;
  35     print join("\n", map { $_->description } @categories), "\n";
  36
  37 =head1 DESCRIPTION
  38
  39 Objects of this class represent a row in the C<categories> 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.
