# 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.
