So I wrote a simple program that pould take a random line for a text file, and write it, but anything within square brackets would be treated as a filename to recurse into. Basically, a simple text substitution system that used a random line from the target file.
Then adding 256 text storage things, some rewriting to output to strings rather than directly, and then other stuff...
Well, I want to share it with the forum, but it isn't good enough for a place of it's own.
So here it is:

(Edit: added some libraries and changed the poor quality srand() mechanism that uses a file to save the last rand() into one that uses time(). The only error with -Wall is about getch(), but I don't know where getch() is implemented...)
This is the place for anyone else to share small programs that aren't really notably good at anything.
