The idea behind the do_set way is that you can binary search (or fancier)
it later without changing the switch() all around.

/* NOTE: destroys input */
void split_colon(char *input, char **postcolon)
  char *pos = strchr(input, ':');
  *pos++ = '\0';
  *postcolon = pos;

char *foo = "Somekeyword: somevalue";
split_colon(foo, &post);
/* foo == "Somekeyword", post == " somevalue" */

Obviously you'll need error checking better than above.  You'd also want to
call skip_spaces() on postcolon if you didn't want the space.

Yes.  sprintascii() is in genwld.c at the moment. strip_cr is in genolc.c

Now I just wish I could do mudlog() without having to convert all the old

Basically you make a file into a 'char *' to play with.  Then you don't
have to worry about how much to read and the operating system pages in
whatever you need.  The other advantage is that the operating system is
free to throw away the memory the file currently takes up because it knows
where to get it again.  If you just read() into malloc() memory, it doesn't
know how to do that.

I generally try not to unless the previous wheel is square or its neat to

There exists a limit beyond a program should not go.  I'm not sure where
that limit would be, but I do know OasisOLC won't read your e-mail.

I had the same sort of idea for defining the menus in OasisOLC.
