# cPanel WHM Account Creator 1.1
###############################################################
# Visit http://www.zubrag.com/scripts/ for updates
###############################################################
# Required parameters:
# - domain - new account domain
# - user - new account username
# - password - new account password
# - package - new account hosting package (plan)
# - email - contact email
#
# Sample run: create-whm-account.php?domain=reseller.com&user=hosting&password=manager&package=unix_500
#
# If no parameters passed then input form will be shown to enter data.
#
# This script can also be run from another PHP script. This may
# be helpful if you have some user interface already in place and 
# want to automatically create WHM accounts from there.
# In this case you have to setup following variables instead of
# passing them as parameters:
# - $user_domain - new account domain
# - $user_name - new account username
# - $user_pass - new account password
# - $user_plan - new account hosting package (plan)
# - $user_email - contact email
