These actions produce a file named "typescript" containing a transcript of the session. Such files may contain backspace characters, which make the print-out look ugly in spots. Before printing the typescript file, issue the command "hugs", load the script "removeBS.hs" and issue the command "main" to Hugs. This command will write file named "typescript.cln" in which the backspaces have be interpreted properly. This file contains no unsightly backspaces. Print it instead of the raw transcript file.
