# Syntax:  findgrep [-w] [-u] [-h] string
#
# Purpose: Searches all files in the current directory and its subdirectories
#          for a given string.
#          If the option -w is specified, findgrep searches for  string  as a
#          word.
#          If the option -u is specified, findgrep distinguishes between upper
#          and lower case letters.
#          The -h flag shows the help info for this command.
