### mergeTemplate

    public static void mergeTemplate(VelocityEngine velocityEngine,
                                     String templateLocation,
                                     Map model,
                                     Writer writer)
                              throws VelocityException

  Merge the specified Velocity template with the given model and write the result to the given Writer.

  Parameters:
    `velocityEngine` - VelocityEngine to work with
    `templateLocation` - the location of template, relative to Velocity's resource loader path
    `model` - the Map that contains model names as keys and model objects as values
    `writer` - the Writer to write the result to
  Throws:
    `VelocityException` - if the template wasn't found or rendering failed

### mergeTemplate

    public static void mergeTemplate(VelocityEngine velocityEngine,
                                     String templateLocation,
                                     String encoding,
                                     Map model,
                                     Writer writer)
                              throws VelocityException

  Merge the specified Velocity template with the given model and write the result to the given Writer.

  Parameters:
    `velocityEngine` - VelocityEngine to work with
    `templateLocation` - the location of template, relative to Velocity's resource loader path
    `encoding` - the encoding of the template file
    `model` - the Map that contains model names as keys and model objects as values
    `writer` - the Writer to write the result to
  Throws:
    `VelocityException` - if the template wasn't found or rendering failed

### mergeTemplateIntoString

    public static String mergeTemplateIntoString(VelocityEngine velocityEngine,
                                                 String templateLocation,
                                                 Map model)
                                          throws VelocityException

  Merge the specified Velocity template with the given model into a String.

  When using this method to prepare a text for a mail to be sent with Spring's mail support, consider wrapping VelocityException in MailPreparationException.

  Parameters:
    `velocityEngine` - VelocityEngine to work with
    `templateLocation` - the location of template, relative to Velocity's resource loader path
    `model` - the Map that contains model names as keys and model objects as values
  Returns:
    the result as String
  Throws:
    `VelocityException` - if the template wasn't found or rendering failed

    `MailPreparationException`

### mergeTemplateIntoString

    public static String mergeTemplateIntoString(VelocityEngine velocityEngine,
                                                 String templateLocation,
                                                 String encoding,
                                                 Map model)
