# ixpm-autoinstall is for automating the install/update process for INEX's
# IXP-Manager - https://github.com/inex/IXP-Manager
# It initially derived heavily from the manual install instructions provided there.

# NB: This autoupdater (wrapper around the autoinstaller to update a running version) is much more of a
#     work in progress, far less portable and not very trustworthy yet...
#
# TODO:
#  * get values from conf file instead of hardcoded
#  * make portable (externalize $_d, $_e, $_null, sed_i(), mkdir_p()
#    from ixpm-autoinstall.sh and source them here and in that script)

# Wrapper for ixpm-autoinstall to update a running installation
# (stopping daemons and backing up original files and db first)
