+=head1 NAME
+
+SL::Form.pm - main data object.
+
+=head1 SYNOPSIS
+
+This is the main data object of Lx-Office.
+Unfortunately it also acts as a god object for certain data retrieval procedures used in the entry points.
+Points of interest for a beginner are:
+
+ - $form->error            - renders a generic error in html. accepts an error message
+ - $form->get_standard_dbh - returns a database connection for the
+
+=head1 SPECIAL FUNCTIONS
+
+=over 4
+
+=item _store_value()
+
+parses a complex var name, and stores it in the form.
+
+syntax:
+  $form->_store_value($key, $value);
+
+keys must start with a string, and can contain various tokens.
+supported key structures are:
+
+1. simple access
+  simple key strings work as expected
+
+  id => $form->{id}
+
+2. hash access.
+  separating two keys by a dot (.) will result in a hash lookup for the inner value
+  this is similar to the behaviour of java and templating mechanisms.
+
+  filter.description => $form->{filter}->{description}
+
+3. array+hashref access
+
+  adding brackets ([]) before the dot will cause the next hash to be put into an array.
+  using [+] instead of [] will force a new array index. this is useful for recurring
+  data structures like part lists. put a [+] into the first varname, and use [] on the
+  following ones.
+
+  repeating these names in your template:
+
+    invoice.items[+].id
+    invoice.items[].parts_id
+
+  will result in:
+
+    $form->{invoice}->{items}->[
+      {
+        id       => ...
+        parts_id => ...
+      },
+      {
+        id       => ...
+        parts_id => ...
+      }
+      ...
+    ]
+
+4. arrays
+
+  using brackets at the end of a name will result in a pure array to be created.
+  note that you mustn't use [+], which is reserved for array+hash access and will
+  result in undefined behaviour in array context.
+
+  filter.status[]  => $form->{status}->[ val1, val2, ... ]
+
+=item update_business PARAMS
+
+PARAMS (not named):
+ \%config,     - config hashref
+ $business_id, - business id
+ $dbh          - optional database handle
+
+handles business (thats customer/vendor types) sequences.
+
+special behaviour for empty strings in customerinitnumber field:
+will in this case not increase the value, and return undef.
+
+=item redirect_header $url
+
+Generates a HTTP redirection header for the new C<$url>. Constructs an
+absolute URL including scheme, host name and port. If C<$url> is a
+relative URL then it is considered relative to Lx-Office base URL.
+
+This function C<die>s if headers have already been created with
+C<$::form-E<gt>header>.
+
+Examples:
+
+  print $::form->redirect_header('oe.pl?action=edit&id=1234');
+  print $::form->redirect_header('http://www.lx-office.org/');
