-//
-// This file defines `absl::StrReplaceAll()`, a general-purpose string
-// replacement function designed for large, arbitrary text substitutions,
-// especially on strings which you are receiving from some other system for
-// further processing (e.g. processing regular expressions, escaping HTML
-// entities, etc.). `StrReplaceAll` is designed to be efficient even when only
-// one substitution is being performed, or when substitution is rare.
-//
-// If the string being modified is known at compile-time, and the substitutions
-// vary, `absl::Substitute()` may be a better choice.
-//
-// Example:
-//
-// std::string html_escaped = absl::StrReplaceAll(user_input, {
-//                                                {"&", "&"},
-//                                                {"<", "&lt;"},
-//                                                {">", "&gt;"},
-//                                                {"\"", "&quot;"},
-//                                                {"'", "&#39;"}});

-// StrReplaceAll()
-//
-// Replaces character sequences within a given string with replacements provided
-// within an initializer list of key/value pairs. Candidate replacements are
-// considered in order as they occur within the string, with earlier matches
-// taking precedence, and longer matches taking precedence for candidates
-// starting at the same position in the string. Once a substitution is made, the
-// replaced text is not considered for any further substitutions.
-//
-// Example:
-//
-//   std::string s = absl::StrReplaceAll(
-//       "$who bought $count #Noun. Thanks $who!",
-//       {{"$count", absl::StrCat(5)},
