  54 =head1 NAME

  56 C4::Branch - Koha branch module
  57
  58 =head1 SYNOPSIS
  59
  60 use C4::Branch;
  61
  62 =head1 DESCRIPTION
  63
  64 The functions in this module deal with branches.
  65
  66 =head1 FUNCTIONS
  67
  68 =head2 GetBranches
  69
  70   $branches = &GetBranches();
  71
  72 Returns informations about ALL branches, IndependentBranches Insensitive.
  73 GetBranchInfo() returns the same information.
  74
  75 Create a branch selector with the following code.
  76

  83         my %row =(value => $thisbranch,
  84                     selected => $selected,
  85                     branchname => $branches->{$thisbranch}->{branchname},
  86                 );
  87         push @branchloop, \%row;
  88     }
  89
