Using versions to store multiple programs in one file

Part of VersioningCategory

Description

Rather than having multiple programs, just have one that compiles for a variety of settings.

Example

/*

//you can version for different os's like so:
version(linux
{
import std.c.linux.linux;
}
version(Win32)
{
import std.c.windows.windows;
}
//or for different environments

version(fast)
{
//whatever makes it runf aster
}
version(small)
{
//whatever makes it smaller
}
