# Subject: Program to add header to Icon program

#
# This program prepends a standard header to an Icon program. It does not
# check to see if the program already has a header.
#
# The first command-line argument is taken as the base
# name of the file; default "foo". The second command-line argument is
# taken as the author; the default is "Ralph E. Griswold" -- with minor
# apologies, I use this program a lot; personalize it for your own
# use.
#
# The new file is brought up in the vi editor.
#
# The file skeleton.icn must be accessible via dopen().
#
############################################################################
#
# Requires: system(), vi(1)
#

# Links: datetime, io
