 calctab package - A language for numeric tables
-version 0.6 2009/03/28
+version 0.6.1 2009/07/12
 
 1 - Introduction
-The calctab package helps the user to typeset a kind of economic table such as invoices, expense notes and liquidation, or other tabular material with a values columns.
-The code computes sum and percentage with floating point numeric method (with the fltpoint package by Eckhart Guthoehrlein) and builds the render table task.
-Economics items may be are independent values or not like sums and percentage on previous values. The language must be expressive concerning together data and its relationships.

 2 - Calctab and xcalctab environments
-The calctab environment allow you to typesetting a table with only one values column beside a label and a description columns.
-In the xcalctab environment the values of two columns are multiplied and the result is printed in a third column.

 Please read the calctab user manual for more information and example.
 
 3 - Language
-A standard tabular environment works well but force the user to think in a generic LaTeX language without a conceptual relation among the items. In addition a lot of formatting commands takes the same relevance of the main data.

 4 - Feedback and language enhancements
-This version waiting for the user help and feedback and somehow a powerful implemented language to adjust all the view property such as row numbering, label type, coloring, etc.
-Finally, I hope in a new infrastructure design which allow to building table with an object oriented language (ool).

+Since the \cmd{add} command not adds new table element in the stack so is easy to insert a subtotal. This is one of the basic rules implicit in the \env{calctab} environment so you are free to add an \cmd{add} row without you worry about following row's computation. In other words, the \cmd{add} command is a \emph{trasparent} math object.
+
 The behaviour of the inner commands is based on these main rules:
 
 \begin{itemize}
     \item Each command typeset one table row;
-    \item the sequence of commands produce the sequence of the table rows;
-    \item the \verb=\perc= and the \verb=\add= commands computes all previous values (with exception to the \verb=\add= row);
-    \item optional command argument provides a relation row language to select item or groups of items.

 \end{itemize}
 
-An independent value is not only a numeric data but also it's defined by a description text. This concept is directly express by the \verb=\amount= command which needs two mandatory arguments: the \emph{description text} and the item \emph{economic consistency}.

 These three commands are available in an environment called \env{calctab} that represents the comprehensive structure of a table.
 
 The code implementation of the inner commands computes the numeric results with the floating point algorithm rounded it with a max of two decimal digit (currently the results are truncated at this fixed precision).
 The number of the commands mandatory argument can be negative.
 
-The \env{calctab} environment manages all the table format elements such as the rows color, the rules, the columns header description text, etc.

 The width of the \ct{} table can be adjust via a standard \LaTeX{} length called \cmd{ctsep} (default value is 8mm). The horizontal space will be add to the central column of the table. The next line is an example:

+\subsubsection{One command, one table}

+\subsubsection{Inner table command}

+\begin{Verbatim}
+\newcommand{\closetable}[1][10]{
+\add{Subtotal}
+\perc{Tax}{#1}
+\add{Total}
+}
+\end{Verbatim}
+
+With this command the user can write shortly:
+
+\begin{Verbatim}
+\begin{calctab}
+   \amount{Cost}{1200}
