// Copyright (c) 2012 The Chromium Authors. All rights reserved.
// Use of this source code is governed by a BSD-style license that can be
// found in the LICENSE file.
// This command-line program converts an effective-TLD data file in UTF-8 from
// the format provided by Mozilla to the format expected by Chrome. This
// program generates an intermediate file which is then used by gperf to
// generate a perfect hash map. The benefit of this approach is that no time is
// spent on program initialization to generate the map of this data.
//
// Running this program finds "effective_tld_names.dat" in the expected location
// in the source checkout and generates "effective_tld_names.gperf" next to it.
//
// Any errors or warnings from this program are recorded in tld_cleanup.log.
//
// In particular, it
// * Strips blank lines and comments, as well as notes for individual rules.
// * Strips a single leading and/or trailing dot from each rule, if present.
// * Logs a warning if a rule contains '!' or '*.' other than at the beginning
// of the rule. (This also catches multiple ! or *. at the start of a rule.)
// * Logs a warning if GURL reports a rule as invalid, but keeps the rule.
// * Canonicalizes each rule's domain by converting it to a GURL and back.
// * Adds explicit rules for true TLDs found in any rule.
// * Marks entries in the file between "// ===BEGIN PRIVATE DOMAINS==="
// and "// ===END PRIVATE DOMAINS===" as private.
