# FINDGREP INFO ########################
PROGRAMINFO="findgrep version 6.
This Script simplifies the recursive search of any given string in a given directory.
It combines find and grep. Results are logged for later viewing and analyzing.
findgrep remembers directories and search strings for following searches."

PROGRAMINFO2="To change the path for logging of queries, please edit \$SAVEFILE in this script. Searches are case insensitive by default. Written by LinuxNetzer. www.netz10.de. contact: linuxnetzer-*-aet-*-netz10.de. findgrep v6 is released under GPL v3."

# CHANGELOG #############################

# Changed to more userfriendly interface. 
# Added many comments for better script reading.
