-* General remarks:
-*  - Variable names and block names are case-insensitive.
-*  - The same variable may be used multiple times within a template.
-*  - Blocks can be nested.
-*  - Multiple blocks with the same name may occur within a template.
-*
-* -* 
-* Public methods:
-*   readTemplateFromFile   - Reads the template from a file.
-*   setTemplateString      - Assigns a new template string.
-*   setVariable            - Sets a template variable.
-*   setVariableEsc         - Sets a template variable to an escaped string value.
-*   variableExists         - Checks whether a template variable exists.
-*   addBlock               - Adds an instance of a template block.
-*   blockExists            - Checks whether a block exists.
-*   reset                  - Clears all variables and blocks.
-*   generateOutput         - Generates the HTML page and writes it to the PHP output stream.
-*   generateOutputToFile   - Generates the HTML page and writes it to a file.
-*   generateOutputToString - Generates the HTML page and writes it to a string.

-* -* Version history:
-* 2001-10-24 Christian d'Heureuse (chdh): VBasic version created.
-* 2002-01-26 Markus Angst: ported to PHP4.
-* 2003-04-07 chdh: changes to adjust to Java version.
-* 2003-07-08 chdh: Method variableExists added. -* Method setVariable changed to trigger an error when the variable does not exist.
-* 2004-04-07 chdh: Parameter isOptional added to method setVariable. -* Licensing changed from GPL to LGPL.
-* 2004-04-18 chdh: Method blockExists added.
-* 2004-10-28 chdh:
-* Method setVariableEsc added.
-* Multiple blocks with the same name may now occur within a template.
-* No error ("unknown command") is generated any more, if a HTML comment starts with "${".
-* 2004-11-06 chdh:
-* "$Include" command implemented.
-* 2004-11-20 chdh:
-* "$Include" command changed so that the command text is not copied to the output file.

+* 2002-01-26 Markus Angst: ported to PHP4.
+* 2003-04-07 chdh: changes to adjust to Java version.
+* 2003-07-08 chdh: Method variableExists added. +* Method setVariable changed to trigger an error when the variable does not exist.
+* 2004-04-07 chdh: Parameter isOptional added to method setVariable. +* Licensing changed from GPL to LGPL.
+* 2004-04-18 chdh: Method blockExists added.
+* 2004-10-28 chdh:
+* Method setVariableEsc added.
+* Multiple blocks with the same name may now occur within a template.
+* No error ("unknown command") is generated any more, if a HTML comment starts with "${".
+* 2004-11-06 chdh:
+* "$Include" command implemented.
+* 2004-11-20 chdh:
+* "$Include" command changed so that the command text is not copied to the output file.
