#detectfile is a fast way to create archives that
#contains file trees and search through them.
#If you have many backup medium you can make
#archives for each one and search for a file into
#them.

#usage:
#Creating an archive
# $ detectfile -c directory_to_examinate arch_file_name
#
#Searching for file
# $ detectfile -f substring_in_file_name
