/*
|

Package syntax parses regular expressions into parse trees and compiles
|
||||
parse trees into programs. Most clients of regular expressions will use the
|
||||
facilities of package regexp (such as Compile and Match) instead of this package.
|
||||
|
||||
Syntax
|
||||
|
||||
The regular expression syntax understood by this package when parsing with the Perl flag is as follows.
|
||||
Parts of the syntax can be disabled by passing alternate flags to Parse.
|
||||
|
||||
.

Unicode character classes are those in unicode.Categories and unicode.Scripts.
