entrance/.scrap contains misleading instructions

symbolic is a non-standard command, and is missing on a default Debian/Ubuntu install:

jaqque@athena:~/bashcrawl/entrance$ cat scrap

# Descend, bold traveller, into the dungeons of Posix,
# which the shadow of Scartaris touches,
# and you will learn the magickal incantations
# of the Wildebeest.
#
# I have done this, in the place of the singing flame:
#
# symlink --symbolic ../../../../.rift portal
#
# [signed] Arnnisen the Gray

jaqque@athena:~/bashcrawl/entrance$ symlink --symbolic ../../../../.rift portal
No command 'symlink' found, did you mean:
 Command 'symlinks' from package 'symlinks' (universe)
symlink: command not found
