       Perl::Critic::Theme - Construct thematic sets of policies.

       This is a helper class for evaluating theme expressions into sets of Policy objects.
       There are no user-serviceable parts here.

       This is considered to be a non-public class.  Its interface is subject to change without

       "new( -rule => $rule_expression )"
	   Returns a reference to a new Perl::Critic::Theme object.  "-rule" is a string
	   expression that evaluates to true or false for each Policy..  See "THEME RULES" for
	   more information.

       "policy_is_thematic( -policy => $policy )"
	   Given a reference to a Perl::Critic::Policy object, this method returns evaluates the
	   rule against the themes that are associated with the Policy.  Returns 1 if the Policy
	   satisfies the rule, 0 otherwise.

       " rule() "
	   Returns the rule expression that was used to construct this Theme.  The rule may have
	   been translated into a normalized expression.  See "THEME RULES" for more information.

       A theme rule is a simple boolean expression, where the operands are the names of any of
       the themes associated with the Perl::Critic::Polices.

       Theme names can be combined with logical operators to form arbitrarily complex
       expressions.  Precedence is the same as normal mathematics, but you can use parentheses to
       enforce precedence as well.  Supported operators are:

	  Operator    Altertative    Example
	  &&	      and	     'pbp && core'
	  ||	      or	     'pbp || (bugs && security)'
	  !	      not	     'pbp && ! (portability || complexity)

       See "CONFIGURATION" in Perl::Critic for more information about customizing the themes for
       each Policy.

       "cook_rule( $rule )"
	   Standardize a rule into a almost executable Perl code.  The "almost" comes from the
	   fact that theme names are left as is.

	   A regular expression that will return the first character in the matched expression
	   that is not valid in a rule.
