+=head1 NAME
+
+SL::MoreCommon.pm - helper functions
+
+=head1 DESCRIPTION
+
+this is a collection of helper functions used in kivitendo.
+Most of them are either obvious or too obscure to care about unless you really have to.
+The exceptions are documented here.
+
+=head2 FUNCTIONS
+
+=over 4
+
+=item save_form
+
+=item restore_form
+
+A lot of the old sql-ledger routines are strictly procedural. They search for params in the $form object, do stuff with it, and return a status code.
+
+Once in a while you'll want something from such a function without altering $form. Yeah, you could rewrite the routine from scratch... not. Just save you form, execute the routine, grab your results, and restore the previous form while you curse at the original design.
+
+=item cross BLOCK ARRAY ARRAY
+
+Evaluates BLOCK for each combination of elements in ARRAY1 and ARRAY2
+and returns a new list consisting of BLOCK's return values.
+The two elements are set to $a and $b.
+Note that those two are aliases to the original value so changing them
+will modify the input arrays.
+
+ # append each to each
+ @a = qw/a b c/;
+ @b = qw/1 2 3/;
+ @x = cross { "$a$b" } @a, @b;
+ # returns a1, a2, a3, b1, b2, b3, c1, c2, c3
+
+As cross expects an array but returns a list it is not directly chainable
+at the moment. This will be corrected in the future.
+
+=item ary_to_hash INDEX_KEY, VALUE_KEY, ARRAY
+
+Returns a hash with the content of ARRAY based on the values of
+INDEX_KEY and VALUE_KEY.
+
+If INDEX_KEY is undefined then the elements of ARRAY are the keys and
+'1' is the value for each of them.
+
+If INDEX_KEY is defined then each element of ARRAY is checked whether
+or not it is a hash. If it is then its element at the position
+INDEX_KEY will be the resulting hash element's key. Otherwise the
+element is assumed to be a blessed reference, and its INDEX_KEY
+function will be called.
+
+The values of the resulting hash follow a similar pattern. If
+VALUE_KEY is undefined then the current element itself is the new hash
+element's value. If the current element is a hash then its element at
+the position VALUE_KEY will be the resulting hash element's
+key. Otherwise the element is assumed to be a blessed reference, and
+its VALUE_KEY function will be called.
