  55
  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, IndependantBranches Insensitive.
  73 GetBranchInfo() returns the same information without the problems of this function
  74 (namespace collision, mainly).
  75
  76 Create a branch selector with the following code.
  77
  78 =head3 in PERL SCRIPT
  79
  80     my $branches = GetBranches;
  81     my @branchloop;
  82     foreach my $thisbranch (sort keys %$branches) {
  83         my $selected = 1 if $thisbranch eq $branch;
  84         my %row =(value => $thisbranch,
  85                     selected => $selected,
  86                     branchname => $branches->{$thisbranch}->{branchname},
  87                 );
  88         push @branchloop, \%row;
  89     }
  90
  91 =head3 in TEMPLATE
