 \chapter{Variables and Variable Types}
 
+Variables are used to contain dynamic content values and can be
+sourced from several locations and limited in scope depending on use.
+Some variable types can be set to reflect script state or are read
+only from other outside sources of data. The following is a list of
+variable types and a brief description of their source:
+
+\begin{itemize}
+
+\item Global - values can be initiaized using the set tag and
+specifying the scope of global. 
+
+\item Local - 
+
+\end{itemize}
+
+\section{Global Variables}
+
+Global is the default if the scope is
+not specified for any function that writes to a variable.

+Operators are used to perform arithmetic or boolean operations on

 \section{sql}
 
+Use the sql tag to specify an sql statement to run on the sql server
+specified in the mysql tag. 
 
+As long as sql statements are executed within the same mysql
+containing tag then the same mysql session is used for each sql
+statement. 
 
 \section{stream}
 
+Use stream tag to output data from the server without waiting for the
+standard output buffering and processing of the JET script. This is
+useful for outputting images and streams for audio and video without
+the server having to load the whole thing into RAM first. 
+
 \section{system}
 
+Use the system tag to execute a bash shell command within the JET
+script. 
+
 \section{tag}
 
+Use the tag tag to define a new tag definition for use within the
+script. 
+
+Tags are normally defined globally and can be used anywhere within the
+script. 
+
+Tags can also be defined within other tags and the scope of those tags
+is only within the defining tag's container. The enclosed tag
+definition will not be available globally. 
+
+\section{until}
+
+Use the until tag to process a container at least once and
+continue to process the container until the specified condition is met. 
+
+Note that this tag always processes the container at least once. 
+
+Be careful not to create a never ending loop by not modifying any of
+the condition parameters specified in the condition clause. 
 
 \section{while}
 
+Use the while tag to process a container if the specified condition is
+true. 
+
+Note that the container may not be processed if the condition is never
+met. 
+
+Be careful not to create a never ending loop by not modifying any of
+the condition parameters specified in the condition clause. 
+
 \section{whiledir}
 
+Use the whiledir tag to loop a directory path to the container for
+processing. 
+
 \section{whilerow}
 
+Use the whilerow tag in combination with mysql and sql tags to provide
+a container to process for each row retrieved by the sql statement. 
+
 \section{write}
 
+Use the write tag to write data to the local file system.
