+# File:         cscope-indexer
+# RCS:          $Header: /cvsroot/cscope/cscope/contrib/xcscope/cscope-indexer,v 1.2 2001/06/28 04:39:47 darrylo Exp $
+# Description:  Script to index files for cscope
+#
+#		This script generates a list of files to index
+#		(cscope.out), which is then (optionally) used to
+#		generate a cscope database.  You can use this script
+#		to just build a list of files, or it can be used to
+#		build a list and database.  This script is not used to
+#		just build a database (skipping the list of files
+#		step), as this can be simply done by just calling
+#		"cscope -b".
+#
+#		Normally, cscope will do its own indexing, but this
+#		script can be used to force indexing.  This is useful
+#		if you need to recurse into subdirectories, or have
+#		many files to index (you can run this script from a
+#		cron job, during the night).  It is especially useful
+#		for large projects, which can contstantly have source
+#		files added and deleted; by using this script, the
+#		changing sources files are automatically handled.
+#
+#		Currently, any paths containing "/CVS/" or "/RCS/" are
+#		stripped out (ignored).
+#
+#		This script is written to use only basic shell features, as
+#		not all shells have advanced features.

+# Usage:
+#
+#     cscope-indexer [ -v ] [-f database_file ] [-i list_file ] [ -l ] [ -r ]
+#
+# where:
+#
+#     -f database_file
+#          Specifies the cscope database file (default: cscope.out).
+#
+#     -i list_file
+#          Specifies the name of the file into which the list of files
+#          to index is placed (default: cscope.files).
+#
+#     -l
+#          Suppress the generation/updating of the cscope database
+#          file.  Only a list of files is generated.
+#
+#     -r
+#          Recurse into subdirectories to locate files to index.
+#          Without this option, only the current directory is
+#          searched.
+#
+#     -v
+#          Be verbose.  Output simple progress messages.
