#Script to check if all the dependencies are ok in a Linux system.
#It is written for Slackware Linux but will work on others distro...hope so ;-)
#but not for the Slackware install cd check code.
#Coded by Pierluigi Previtali slack@NOSPAMslack.z00.it .
#inspired by Cameron Kerr cameron.kerr@NOSPAMparadise.net.nz .
#read the report in /tmp/ldd_report .
#This script will search binary files and test with the ldd command 
#if the dependencies are ok and will make a report.
#Code released under GPL2
