# About the encoding:
#
#   The Digest::MD5 module is necessary to use the encrypted password system.
#   When the software cannot found the Digest::MD5 module,
#     encoding is automatically disabled ($passenc=0), which allows
#     to use this program in any cases.
#
#-------------------------------------------------------------------------
# How to use ladmin with UNIX:
#
# You excecute ladmin as a standard command.
#  <Example of preparation to have an access to ladmin>
#    $ mv ladmin ladmin_org
#    $ nkf -eLu ladmin_org > ladmin
#    $ chmod 700 ladmin
#  <Example to start directly ladmin>
#    $ perl ladmin
