# The LearningOnline Network with CAPA
#
# A CGI script that decompresses compressed files for mass uploading into
# construction space
####
#Things still todo,
#It has been tabinated
#Now uses strict! with added feature of making everything very strict!
#about 50% through rewriting things to use split and join
#still have a lot of debugging statements that will go away after I get it to work ok(along with all the <br>'s)
#still have to rewrite the refresh tag to work right, its broken
#the whole thing is broken right now
#will rename the variables and reorder most of the script to make it more sane
#improve the general readability of the whole thing, because unlike C everyone gets to look at it, so it has to be readable
#will get to it tommorrow night as I have a calc test to "pass" yea, or something like that :0)
