## Overview

The SimpleIPC unit provides classes to implement a simple, one-way IPC mechanism using string messages. It provides a TSimpleIPCServer component for the server, and a TSimpleIPCClient component for the client. The components are cross-platform, and should work both on Windows and unix-like systems.

The Unix implementation of the SimpleIPC unit uses file-based sockets. It will attempt to clean up any registered server socket files that were not removed cleanly.

It does this in the unit finalization code. It does not install a signal handler by itself, that is the task of the programmer. But program crashes (access violations and such) that are handled by the RTL will be handled gracefully.

This also means that if the process is killed with the KILL signal, it has no chance of removing the files (KILL signals cannot be caught), in which case socket files may remain in the filesystem.
