  51 =head1 NAME
  52
  53 C4::Branch - Koha branch module
  54
  55 =head1 SYNOPSIS
  56
  57 use C4::Branch;
  58
  59 =head1 DESCRIPTION
  60
  61 The functions in this module deal with branches.
  62
  63 =head1 FUNCTIONS
  64
  65 =head2 GetBranches
  66
  67   $branches = &GetBranches();
  68
  69   Returns informations about ALL branches, IndependantBranches Insensitive.
  70   GetBranchInfo() returns the same information without the problems of this function
  71   (namespace collision, mainly).
  72   Create a branch selector with the following code.
  73
  74 =head3 in PERL SCRIPT
  75
  76     my $branches = GetBranches;
  77     my @branchloop;
  78     foreach my $thisbranch (sort keys %$branches) {
  79         my $selected = 1 if $thisbranch eq $branch;
  80         my %row =(value => $thisbranch,
  81                     selected => $selected,
  82                     branchname => $branches->{$thisbranch}->{branchname},
  83                 );
  84         push @branchloop, \%row;
  85     }
  86
  87 =head3 in TEMPLATE
  88
  89     <select name="branch">
  90         <option value="">Default</option>
