# Note: cryptemail() function will print e-mail address such a way that #
# only browser will understand it, and display the correct text #
# corresponding to each character. This function is very useful #
# to stop SPAM. It will make it hard for normal Web Spider/Crawler #
# or any custom made e-mail harvesting script which gets all #
# e-mail addresses for a web-page,dump in the database & do SPAM. #
# To see the demo- just run this script, and you will understand it. #
