# Subject: Program to lump linked Icon source files

#
# usage: ilump [file...]
#
# ilump copies one or more Icon source files, incorporating recursively
# the source code for files named by "link" directives. This produces a
# standalone source program in one file, which is useful with certain
# profiling and visualization tools.
#
# Searching for link'd source files is similar to the action of Iconc
# under UNIX. If a link'd file is not found in the current directory,
# directories specified by the LPATH environment variable are tried.
