# This is the first attempt to write something useful to break all those
# wonderful pieces-of-art that obfuscated code represents. How do they work?
# How can i read them more easily? Is this Reverse Engineering? I just
# started learning Perl and Obfuscation, and i wanted something to help when
# learning from others' scripts. ASCII-art-formatted scripts are really hard
# to read. this crumb of code helps a little, and I look for help to improve
# it. For instance, it should detect and properly format regular expressions
# which do not use regular "/" and hopefully better format loops!
# And finally, how may the "enlightenment" come from "obfuscation" ?
# Follow the light, and leave the Dark Side! ;-)
#
# (by the way, there's always something fascinating in darkness...
# i like obfu!!! ;-P )
