Yes, it's amazing. A book this long, and some things still weren't covered. The footnotes contain additional helpful information.

The purpose of this section is not to teach you about the things listed here, but merely to provide a list. You'll need to go to Programming Perl, the perl documentation, the Perl FAQ, the Perl for Win32 FAQ, the HTML documents in CPAN's doc directory, the Usenet support groups, or the Perl mailing lists to get further information.

D.1 Full Interprocess Communications

Yes, Perl can do networking. Beyond the TCP/IP stream sockets discussed in Appendix C, Networking Clients, Perl also supports UDP-based message passing, named and anonymous pipes, semaphores, mutexes, process control, IPC, signal handling, and more. See Chapter 6 of Programming Perl or the perlipc documentation for standard modules, and the networking section of the CPAN modules directory for third-party modules.
