# iplweb [-ipl source] [dest]
#
# Uses an environment variable IPL which is a path to the Icon Program Library
# as a default if -ipl is not specified, dest is the current directory if not
# specified.
#
# Generates HTML directory in dest and makes an index to gprogs, gprocs,
# procs, and progs directories under HTML. In each of these directories
# is a .html file for each of the .icn files in the referenced directory.
# A index to all of these files is also generated. Each of the .html files
# contains the IPL standard comment header info inside.
