| 150 | |
| 151 | Gruntmaster::Daemon - Perl extension for blah blah blah |

| 158 | =head1 DESCRIPTION |
| 159 | |
| 160 | Stub documentation for Gruntmaster::Daemon, created by h2xs. It looks like the |
| 161 | author of the extension was negligent enough to leave the stub |
| 162 | unedited. |
| 163 | |
| 164 | Blah blah blah. |

| 170 | related modules or operating system documentation (such as man pages |
| 171 | in UNIX), or any relevant external documentation such as RFCs or |
| 172 | standards. |
