| 25 | Package syntax parses regular expressions into parse trees and compiles |
| 26 | parse trees into programs. Most clients of regular expressions will use the |
| 27 | facilities of package regexp (such as Compile and Match) instead of this package. |

| 31 | The regular expression syntax understood by this package when parsing with the Perl flag is as follows. |
| 32 | Parts of the syntax can be disabled by passing alternate flags to Parse. |
