37             =head1 DESCRIPTION
38              
39             This module implements a rare form of IPC by sending Morse-like signals through C and C. Both of those signals are used, so you won't be able to keep them for something else when you use this module.

49             But, seriously, use something else for your IPC. :)

51             =head1 CAVEATS
52              
53             When the same signal is sent several times in a row to a process, the POSIX standard does not guarantee that the relevant signal handler will be called for each of the notifications.
54             This will result in malformed messages if the transfer speed is so high that the operating system does not have the time to call the signal handler for each bit.
55              
56             =head1 DEPENDENCIES
57              
58             You need the complete L distribution.
59              
60             L (standard since perl 5), L (idem) and L (since perl 5.7.3) are also required.

67              
68             L for information about signals in perl.

70             For truly useful IPC, search for shared memory, pipes and semaphores.
