/**
 * <foreach> task
 *
 * Task definition for the foreach task.  This task takes a list with
 * delimited values, and executes a target with set param.
 *
 * Usage:
 * <foreach list="values" target="targ" param="name" delimiter="|" />
 *
 * Attributes:
 * list      --> The list of values to process, with the delimiter character,
 *               indicated by the "delimiter" attribute, separating each value.
 * target    --> The target to call for each token, passing the token as the
 *               parameter with the name indicated by the "param" attribute.
 * param     --> The name of the parameter to pass the tokens in as to the
 *               target.
 * delimiter --> The delimiter string that separates the values in the "list"
 *               parameter.  The default is ",".
