# This script asks the user for a mush name and makes a copy of the
# game/ directory called <mush>/. It also rewrites the restart script
# to <mush>.restart and mush.cnf (which it calls <mush>.cnf) to
# make it easier to keep track of multiple MUSHes.

Welcome. This script creates a game directory for a MUSH and 
customizes the files in order to make running multiple MUSHes
easier. This is still experimental, but should not affect
any of your files in standard MUSH directories (game, src, hdrs, etc.)

When choosing the name for your directory, use a short version of
the MUSH name. For example, if you MUSH was called Fallen Angels MUSH,
you might choose 'fallen' or 'fa'. Use only upper- or lower-case
letters and numbers in directory names.
