# Commentary:
#
# Create the file given by the variable 'clib_list' below, and place in that
# file the full path for each C, C++ or Objective-C library that you want
# scanned for symbol names. One filename per line. Do not quote the
# filenames.
#
# Handles exact name matches only. Echos and exits with same output value.
# Either 1 if symbol is found or 0 if not.
# Code:
# Create this file and place in the file the full path for each C, C++ or
# Objective-C library that you want scanned for symbol names. One filename
# per line. Do not quote the filenames.
#
set clib_list = "~/.CLIBS-LIST"
# This file will automatically be created to cache the symbol names.
# Remove it if you ever want to rebuild the symbol table.
