All these fix*** scripts ?????

Hey guys I noticed in /scripts almost everything has been overwritten on Aug23

Examples:

fixadmin*
fixcartwithsuexec*
fixcgiwrap*
fixinterchange*
fixinterchangeperm*
fixlibnet*
fixndc*
fixperl*
fixpop*
fixrelayd*
fixtrojans*
fixvaliases*
fixwebalizer*
fixwebmail*
fixwwwdir*

Are we supposed to be using these to fix problems we may or maynot know about. Do they automarically run somehow. Could someone please post a purpose for each script and what to look for if we would need to run it. What\'s an issue with ever box and with only some. THanks.
