I'm having an issue with the similar helpfile snippet. Certain helpfiles if you try to read them (or a close syntax to the helpfile) will crash the MUD instantly, but the gdb will look like a loop.
Is there anyway to set a variable limit so it doesn't do this?

// Main function of Similar Helpfiles Snippet by Senir. It loops through all of the
// helpfiles, using the string matching function defined to find the closest matching
// helpfiles to the argument. It then checks for singles. Then, if matching helpfiles
// are found at all, it loops through and prints out the closest matching helpfiles.
// If its a single(there's only one), it opens the helpfile.
