/usr/bin/make_filelists

#!/bin/sh

# On the command line, list the source code directories, e.g.:
#    /usr/src/redhat/BUILD/*
# This command creates a set of directories paralleling the source code
# directories, with a file named "filelist" listing all the files.

# This script goes through some trouble to turn all relative references
# into absolute pathnames, to make sure that the intended files
# are always referenced. Conceivably the current directory isn't the
# data directory and the parameters given use relative addressing,
# and we need to fix all that here.

# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
