  55 C4::Branch - Koha branch module
  56
  57 =head1 SYNOPSIS
  58
  59 use C4::Branch;
  60
  61 =head1 DESCRIPTION
  62
  63 The functions in this module deal with branches.
  64
  65 =head1 FUNCTIONS
  66
  67 =head2 GetBranches
  68
  69   $branches = &GetBranches();
  70
  71 Returns informations about ALL branches, IndependantBranches Insensitive.
  72 GetBranchInfo() returns the same information without the problems of this function
  73 (namespace collision, mainly).
  74
  75 Create a branch selector with the following code.
  76
  77 =head3 in PERL SCRIPT
  78
  79     my $branches = GetBranches;
  80     my @branchloop;
  81     foreach my $thisbranch (sort keys %$branches) {
  82         my $selected = 1 if $thisbranch eq $branch;
  83         my %row =(value => $thisbranch,
  84                     selected => $selected,
  85                     branchname => $branches->{$thisbranch}->{branchname},
  86                 );
  87         push @branchloop, \%row;
  88     }
  89
  90 =head3 in TEMPLATE
  91
  92     <select name="branch">
  93         <option value="">Default</option>
